Covid-19, the impact of university return

For many reasons, it is important for universities to re-open in the autumn, but it is also clear that this is a high-risk endeavour: bringing around 2% of the UK population together in close proximity for 10 to 12 weeks and then re-dispersing them at Christmas.

When I first estimated the actual size of the impact I was, to be honest, shocked; it was a turning point for me. With an academic hat on I can play with the numbers as an intellectual exercise, but we are talking about many, many thousands of lives at risk, the vast majority outside the university itself, with the communities around universities most at risk.

I have tried to think of easy, gentle and diplomatic ways of expressing this, but there are none; we seem in danger of creating killing zones around our places of learning.

At the very best, outbreaks will be detected early, and instead of massive deaths we will see substantial lockdowns in many university cities across the UK with the corresponding social and economic costs, which will create schisms between ‘town and gown’ that may poison civic relationships for years to come.

In the early months of the year many of us in the university sector watched with horror as we watched the Covid-19 numbers rising and could see where this would end. The eventual first ‘wave’ and its devastating death toll did not need sophisticated modelling to predict; in the intervening months it has played out precisely as expected. At that point the political will was clearly set and time was short; there was little we could do but shake our heads in despair and feel the pain of seeing our predictions become reality as the numbers grew, each number a person, each person a community.

Across the sector, many are worried about the implications of the return of students and staff in the autumn, but structurally the nature of the HE sector in the UK makes it near impossible even for individual universities to take sufficient steps to mitigate it, let alone individual academics.

Doing the sums

For some time, universities across the UK have been preparing for the re-opening, working out ways to reduce the risk. There has been a mathematical modelling working group trying to assess the impact of various measures, as well as much activity at individual institutions.  It appears too that SAGE has highlighted that universities pose a potential risk [SN], but this seems to have gone cold and universities are coping as best they can with apparently no national plan. Universities UK have issued guidance to universities on what to do as they emerge from lockdown [UUKa], but it does not include an estimate of the scale of the problem.

As I said, the turning point for me came when I realised just how bad this could be. As with the early national growth pattern, it does not require complex mathematics to assess, within rough ranges, the potential impact; and even the most conservative estimates are terrifying.

We know from freshers’ flu that infections spread quickly amongst the student community.  The social life is precisely why many students relocate to distant cities.  Without strong measures to control student infections it is clear that Covid-19 will spread rapidly on campuses, leading to thousands of cases in each university. Students themselves are at low (though not zero) risk of dying or having serious complications from Covid-19, but if there is even small ‘leakage’ into the surrounding community (via university staff, transport systems, stay-at-home students or night life), then the impact is catastrophic.

For a mid-sized university of 20,000 students, let’s say only 1 in 20 become infected during the term; that is around 1,000 student cases. As a very conservative estimate, let’s assume just one community infection for every 10 infected students. If city bars are open this figure will almost certainly be much higher, but we’ll take a very low estimate. In this case, we are looking at 100 initial community cases.

Now 100 additional cases is already potentially enough to cause a handful of deaths, but we have got used to trading off social benefits against health costs; for any activity there is always a level of risk that we are prepared to accept.

However, the one bit of mathematics you do need to know is the way that a relatively small R number still leads to a substantial number of cases. For example, an R of 0.9 means for every initial infection the total number of infections is actually 10 times higher (in general 1/(1-R), see [Dx1]).  When R is greater than 1 the effect is worse still, with the impact only limited when some additional societal measure kicks in, such as a vaccine or local lockdown.

A relatively conservative estimate for R in the autumn is 1.5 [AMS]. For R =1.5, those initial 100 community cases magnify to over 10,000 within 5 weeks and more than 600,000 within 10 weeks. Even with the most optimistic winter rate of 1.2, those 100 initial community infections will give rise to 20,000 cases by the end of a term.

That is for a single university.

With a mortality rate of 1% and the most optimistic figures, this means that each university will cause hundreds of deaths.  In other words, the universities in the UK will collectively create as many infections as the entire first wave.  At even slightly less optimistic figures, the impact is even more devastating.

Why return at all?

Given the potential dangers, why are universities returning at all in the autumn instead of continuing with fully online provision?

In many areas of life there is a trade-off to be made between, on the one hand, the immediate Covid-19 health impacts and, on the other, a variety of issues: social, educational, economic, and also longer term and indirect mental and physical health implications. This is no less true when we consider the re-opening of universities.

Social implications: We know that the lockdown has caused a significant increase in mental health problems amongst young people, for a variety of reasons: the social isolation itself, pressures on families, general anxiety about the disease, and of course worries about future education and jobs. Some of the arguments are similar to those for schools except that universities do not provide a ‘child minding’ role. Crucially, for both schools and universities, we know that online education is least effective for those who are already most economically deprived, not least because of continued poor access to digital technology. We risk creating a missed generation and deepening existing fractures in civil society.

Furthermore, the critical role of university research has been evident during the Covid crisis, from the development of new treatments to practical use of infrastructure for rapid production of PPE. Ongoing, the initial wave has emphasised the need for more medical training.  Of course, both education and research will also be critical for ‘post-Covid’ recovery.

Economic situation: Across the UK, universities generate £95 billion in gross output and support nearly a million jobs (2014–2015 data, [UUKb]).  Looking at Wales in particular, the HE sector “employs 17,300 full-time members of staff and spending by students and visitors supports an estimated 50,000 jobs across Wales”. At the same time the sector is particularly vulnerable to the effects of Covid-19 [HoC]. Universities across the UK were already financially straitened due to a combination of demographics and Brexit, leading to significant cost-cutting including job cuts [BBCa].  Covid-19 has intensified this; a Wales Fiscal Analysis briefing paper in May [WFA] suggests that Welsh universities may see a shortfall due to Covid-19 of between £100m and £140m. More recent estimates suggest that this may be understating the problem, if anything. Cardiff University alone is warning of a £168m fall in income [WO] and Sir Deian Hopkin, former Vice Chancellor of London South Bank and advisor to the Welsh Assembly, talks of a “perfect storm” in the university system [BBCb].

Government support has been minimal. The rules for Covid-19 furlough meant that universities were only able to take minimal advantage of the scheme. There has been some support in terms of general advice, reducing bureaucratic overheads and rescheduling payments to help university cashflow, but this has largely been within existing budgets, not new funding. The Welsh government has announced an FE/HE £50m support package with £27m targeting universities [WG], but this is small compared with predicted losses.

Universities across the UK have already cut casual teaching (the increase in zero-hour contracts has been a concern in HE for some years) and many have introduced voluntary severance schemes.  At the same time the competition over UK students has intensified in a bid to make up for reduced international numbers. Yet one of the principal ways to attract students is to maximise the amount of in-person teaching.

What is being done

To some extent, as in so many areas, coronavirus has exposed the structural weaknesses that have been developing in the university sector for the past 30 years. Universities have been forced to compete constantly and are measured in terms of student experience above educational impact. Society as a whole has been bombarded with messages that focus on individual success and safety rather than communal goals, and most current students have grown up in this context. This focus has been very evident in the majority of Covid-19 information and reporting [Dx2].

Everything we do is set against this backdrop, which both fundamentally limits what universities are able to do individually, and at the same time makes them responsible.  This is not to say that universities are not sharing good practice, both in top down efforts such as through Universities UK and direct contacts between senior management, and from the bottom up via person-to-person contacts and through subject-specific organisations such as CPHC.

Typically, universities are planning to retain some level of in-person teaching for small tutorials while completely or largely moving large-class activities such as lectures to online delivery, some live, some recorded. This will help to remove some student–student contact during teaching. Furthermore, many universities have discussed ways in which students could be formed into bubbles. At a large scale that could involve having rooms or buildings dedicated to a particular subject/year group for a day.  At a finer scale it has been suggested that students could be grouped into social/study bubbles of around ten or a dozen who are housed together in student accommodation and are also grouped for study purposes.

My own modelling of student bubbles [Dx3] suggests that while reducing the level of transmission, the impact is rapidly eroded if the bubbles are at all porous.  For example, if the small bubbles break and transmission hits whole year groups (80–200 students), the impact on outside communities becomes unacceptable. For students on campus the temptation to break these bubbles will be intense, both at an individual level and through bars and similar venues.  For those living at home, the complexities are even greater, and crucially they are a primary vector into the local community.

Combined with, or instead of, social/study bubbles some universities are looking at track and trace. Some are developing their own solutions both in terms of apps and regular testing programmes, but more will use normal health systems.  In Wales, for example, Public Health Wales regard university staff as a priority group for Covid-19 testing, although this is reactive (symptoms-based) rather than proactive (regular testing).

Dr Hans Kluge, the Europe regional director for the World Health Organization and others have warned that global surges across the world, including in Europe, are being driven by infections amongst younger people [BBCc].  He highlights the need to engage young people more in the science, a call that is reflected in a recent survey by the British Science Association which found that nine out of ten young people felt ignored by scientists and politicians [BSA].

As of 27th July, the UK Department for Education were “working to” two scenarios “Effective containment and testing” (reduce growth on campuses and reactive local lockdowns) and “On and off restrictions” (delaying all in-person teaching until January) [DfE].  Jim Dickinson has collated and analysed current advice and work at various government and advisory bodies including the DfE report above and SAGE, but so far there seems to be no public quantification of the risk [JD].

What can we do?

I think it is fair to say that the vast majority of high-level advice from national governments and pan-University bodies, and most individual university thinking, has been driven by safety concerns for students and staff rather than the potentially far more serious implications for society at large.

As with so many aspects of this crisis, the first step is to recognise there is a problem.

Within universitiesacknowledge that the risk level will be far higher than in society at large because the case load will be far higher. How much higher will depend on mitigating measures, but whereas general population levels by the start of term may be as low as 1 in 5,000, the rate amongst students will be an order of magnitude higher, comparable with general levels during the peak of the ‘first wave’. This means that advice, particularly for at risk groups, which is targeted at national levels, needs to be re-thought within the university context. This means that advice that is targeted at national levels, particularly for at risk groups, needs to be re-thought within the university context.  Individual vulnerable students are already worried [BBCd]. Chinese and Asian students seem more aware of the personal dangers and it is noticeable that both within the UK and in the US the universities with the greatest number of international students are more risk averse. University staff (academics, cleaners, security) will include more at risk individuals than the student body. It is hard to quantify, but the risk level will considerably higher than, say, a restaurant or pub, though of course lower than for front line medical staff. Even if it is ‘safe’ for vulnerable groups to come out of shielding in general society, it may not be safe in the context of the university. This will be difficult to manage: even if the university does not force vulnerable staff to return, the long-term culture of vocational commitment may make some people take unacceptable risks.

Outside the universities, local councils, national governments and communities need to be aware of the increased risks when the universities reopen, just as seaside towns have braced themselves for tourist surges post-lockdown. While SAGE has noted that universities may be an ‘amplifier’, the extent does not appear (at least publicly) to have been quantified.  In Aberdeen recently a cluster around a small number of pubs has caused the whole city to return to lockdown, and it is hard to imagine that we won’t see similar incidents around universities. This may lead to hard decisions, as has been discussed, between opening schools or pubs [BBCe] – city centre bars may well need to be re-thought. Universities benefit communities substantially both economically and educationally. For individual universities alone the costs of, say, weekly testing of students and staff would be prohibitive, but when seen in terms of regional or national health protection these may well be worthwhile. Although this is a ‘for example’ it could well be critical given the likelihood of large numbers of asymptomatic student cases.

Educate students – this is of course what we do as universities!  Covid-19 will be a live topic for every student, but they may well have many of the misconceptions that permeate popular discourse.  Can we help them become more aware of the aspects that connect to their own disciplines and hence to become ambassadors of good practice amongst their peers? Within maths and computing we can look at models and data analysis, which could be used in other scientific areas where these are taught.  Medicine is obvious and design and engineering students might have examples around PPE or ventilators. In architecture we can think about flows within buildings, ventilation, and design for hygiene (e.g. places to wash your hands in public spaces that aren’t inside a toilet!). In literature, there is pandemic fiction from Journal of the Plague Year to La Peste, and in economics we have examples of externalities (and if you leave externalities until a specialised final year option, rethink a 21st century economics syllabus!).

Time to act

On March 16, I posted on Facebook, “One week left to save the UK – and WE CAN DO IT.” Fortunately, we have more time now to ensure a safe university year but we need to act immediately to use that time effectively. We can do it.

Is Corbynism dead? The data says not.

The December 12th election saw the most disasterous Labour defeat in nearly a century and the collapse of the ‘red wall’ of Labour heartlands in the North-East. Jeremy Corbyn and John McDonnell are standing down in the New Year, and the vultures are gathering to pick the meagre bones of Corbyn’s political body.

Many Labour canvasers reported that on the doors the problem was four parts Corbyn for every one part Brexit. The message is clear, Corbyn was toxic on the doorstep and Labour needs a change.

But the numbers tell a different story.

Labour’s vote share fell dramatically from the surprise successes of 2017, when Corbyn’s campaign charisma unexpectedly set back Teresa May’s ambition to win the sort of majority that Boris Johnson has today.

But if you look before that to 2015,, the picture is less clear

.Comparing the recent election with 2015, the Labour share of the vote in 2019 is actually higher than its vote share in 2015. Yes, Labour is still performing better under the avowedly socialist Jeremy Corbyn than it did under ‘centrist’ Ed Miliband.

The difference between David Cameron’s small majority and Boris Johnson’s landslide is predominantly about the collapse of the UKIP/Brexit vote, with the hard Leavers exchanging Farage for Johnson. In 2017, Labour took a soft Brexit position, which, while annoying many Corbyn supporters at the time, seemed to hold onto many of the Leave voters who last week voted Conservative in Labour heartlands

Increasing vote share since 2015 is remarkable in the face of long-term excoriating press attacks against Jeremy Corbyn personally and a Conservative Facebook ad campaign that fact checkers rated as 88% false, not forgetting persistent undermining by sections of the Labour party itself.

More crucial is who voted for Labour and Conservative. It has always been the case that voters drift right as they age, often favouring economic security over youthful idealism. However this has dramatically shifted in the last few years. Conservative support in younger age groups has crashed utterly and it is now predominantly a party of the old. The Tory Party has effectively mortgaged its future for current electoral success.

This is evident in the demographics of voting on Dec 12th collected by Lord Ashcroft’s post-vote poll. Labour has a vast lead over Conservative in voters under 45, whereas Conservative vote share, which is over 60% in the over 65’s, shrinks to less than 20% in the under 25s.

These under 45s have lived entirely under the neoliberal individualism that started with Thatcher and adopted in large part by New Labour and Tory governments since. They have seen it, and rejected it. A generation is growing who are looking beyond themselves, recognising the disastrous impacts of past policies of all governments on the environment and humanity, and believing in the power of society to transform, not just their own lives, but those of the whole nation and world.

As Labour chooses its new leader, it should ponder whether it wants to revert to the old policies and combat the Tories for the votes of the old, or embrace the spirit of hope and change that has galvanised the youth of the country.

Rich tea biscuits, sugar lumps and Bournville chocolate

I forgot.

How could I forget?

Memory is a fickle thing, not metal storage shelves, or neat filing drawers, but like the tide throwing up flotsam of your past and then withdrawing, just traces in the sand.

We had been sorting boxes long in storage, and I had made my way through plastic crates full of old screws, hinges, locks without keys, and half window-latches. Some I had collected myself over the years, some I’d inherited from Fiona’s grandpa, and some were my dad’s, accreted through a life as builder, carpenter and maintainer of the old Victorian terrace where I was born. All were coated with that dusty brown patina of age, not the rich iridescent rust of wet, but the dull discolouration that rubs off on your hands and leaves small scatterings on the bottom of tins.

There had been one tin, full of such scatterings, and it had gone into the metal recycling box, amongst others.

I had discarded the brown Tupperware box in which I’d kept my own collection of reusable screws as a boy, a few ‘liberated’ from secondary school desks when it seemed fun to see how many screws you could remove from the lids whilst still leaving them, at least apparently, intact.

What would dad have thought? Maybe some would have been the same desks he had repaired when I had still been in infant school.   A few times a year he would be in our school, repairing desks and chairs – in those days all wood. It is likely he also visited the high school where I eventually ended up, wondering how the lids got loose as a previous generation of school children had a short-lived craze of minor vandalism. How many of the scored and inked images and slogans on the desks where I later sat had been there when he had touched them.

The touch of an object, the feel of it under your fingers, bringing back the past. Only it didn’t, the tin was cast thoughtlessly amongst the decaying ironmongery, detritus of a save-it-just-in-case mentality inherited from those who had seen one or two world wars.

Only after, I remembered.

The tin was long and thin, perhaps ten inches long and two and a half or three wide; square in cross-section; I always assumed it was designed for cream crackers. The lid was large-chequered white and red, with an embossed pattern highlighted in long faded gold, but I only half remember, the way you do with things so intimate, so normal, they are merely the background.

Is it always the way that the things that are closest, most dear, are most easily forgotten?

I took no photograph.

It is gone.

I always say, as a tease, that the smell of meths is the smell of childhood; it reminds me of my dad. And it is true.

He was no drinker, certainly not when I knew him, who knows in his youth. In the sideboard cupboard there was a bottle of cherry brandy that I never recall being opened. Did mum and dad sometimes have a small glass after Jacqui and I had gone to bed? I only ever recall very occasional glasses of sherry at Christmas, and maybe that was only mum.

The smell of meths was surgical spirit; twice a day, regular as the clock that was also wound daily, he would inject insulin. Small bottles with round rubber tops, the needle reused, none of today’s disposable needles, or discreet pens, but his trousers wound down and the needle pressed into his thigh, the skin and needle cleaned with cotton wool soaked in the clear spirit. I wonder how many times he reused the needle; I guess until it was too blunt to break the skin.

When a little older, I recall going together to Cardiff Infirmary, I assume for a check-up – the dull post-war institutional painted corridors, and that smell of hospital … soap and disinfectant, and in those days I’m sure also a touch of meths. I do not know whether it was just once or many times, and why I recall it being just the two of us – maybe it was when Jacqui had started school and I had not, or perhaps Jacqui had gone with mum somewhere, or maybe just that soliloquy of childhood that sees everything through one’s own eyes, forgetting that others were there too.

But in my earliest memories, not the hospital, just the smell, the needle and, in every drawer, handbag, and car shelf, sugar lumps and gold wrapped bundles of Bournville chocolate.

When we went out for the day, or drove away on holiday, mid-morning and mid-afternoon we would always stop for a cup of tea and a bite to eat. Then as now, injected insulin was only half the cure; he had to be careful to eat regularly.

In the summer, on a fine day, we would park the car. Dad would take out a Camping Gaz stove from its blue metal box and the kettle would boil while Jacqui and I played in the sun or sat in the back of the car with a sticky-back-plastic-covered plank as a table.

At other times there were cafés, some with Formica topped tables and counters, others oak panelled – always in those days waitress service. Toasted tea-cakes are still a comfort food.

If we stopped for lunch then we would often have soup with crusty rolls. I’m sure they were in the local bakers too, but I always associate those rolls with days out and restaurants. Jacqui and I would pull out the moist white bread from the middle with our fingers, making mouse houses from the hollow crusts, and then, of course, finish with the crusty parts themselves, still the best portion of any loaf.

Neither dad nor mum took sugar in their tea, but on the table there would always be a bowl full of sugar: sometimes naked white lumps piled high, tempting for a small child, and maybe Jacqui and I would be allowed one each to suck.   Sometimes they came in little paper packets, two bundled together – standard dose for a cup of tea – and, if they did, dad would take a few and add them to his collection, for emergencies, if he felt low on sugar, or if for some reason we were late eating.

Once, I recall dad getting angry and shouting at home, a thing rare enough that I remember it. After a while he and mum realised that he had not eaten, and his temper dissolved as his sugar level rose.

The diabetes was managed, part of the background, one of those things so intimate, so common they are not thought about, but never entirely forgotten.

Once dad broke his toe whilst moving a table in the church schoolroom. His foot was in plaster for weeks, but the worry was always that gangrene would set in.

Only later, after dad had gone, I discovered that one of his brothers had died in the 1920s, still in the early days of insulin treatment when they were trying to understand the correct dosages. The insulin prolonged his brother’s life, but also, in the end, killed him.

I always assume dad’s diabetes was late-onset, otherwise he would never have lived until Jacqui and I were born. Late enough that insulin was better understood. Perhaps it had come at a time of stress, in the 1940s when he divorced his first wife, or when his second wife died.

Nowadays, whenever I have a blood test myself, I always ask about the sugar levels.

And the tin?

At home, cups of tea were as much a ritual, dad’s cup bigger than mum’s, but always a cup and saucer; mugs for tea were still many years off. Jacqui and I learnt to drink tea from dad’s saucer. He would pour a little tea on the saucer, blow it and let us sip the cool liquid. It was not just for us, but a trick he sometimes used himself to cool his tea rapidly – a habit from his work as a carpenter to drink quickly in short tea breaks.

With the tea there were no custard creams or bourbons, no chocolate biscuits, nothing iced topped nor anything too sweet, but instead rich tea fingers, thin oval-shaped biscuits with crimped edges. Dad would have two, resting on his saucer and then dunked in the tea until they were soft and warm.

They came in two kinds, one in blue and white packets and slightly lighter in colour, similar in taste to the thicker, round rich-tea biscuits that are more common today; the others in clear packets, with a darker colour and a subtly richer, more savoury, almost nutty taste.

I don’t remember now whether we regularly ate them too as small children or whether they were a grown-up thing. I do recall Jacobs Club biscuits as a treat, always the orange ones. Later as an older child, when I had my own tea, I was always torn between the soft melting texture of dunked finger biscuits, or nibbling them, first around the edge, removing just a few millimetres of the neat crimping, before starting at one end – then, with rodent-like reciprocating teeth, reducing them to sawdust-like powder in my mouth.

The rich tea fingers lived in a tin, and the tin on the sideboard, always.

Pantoum in Eindhoven

While sorting some old files I came across a small pack of notes, stapled together.  They were clearly written in a bar (the beer glasses are a give away!), and the notes mention Eindhoven.

I then remembered.  On one of my visits to Eindhoven, either teaching USI students at TU/e, or for the Desire conference,  I was sitting with someone at a bar, I think waiting for others to join us and I was describing the pantoum, a Malayan poetry form I had originally read about in “The Making of a Poem: A Norton Anthology of Poetic Form“.  This is a lovely book I was given for birthday or Christmas some years ago, that describes many poetical forms, some common such as the sonnet, others, like the pantoum, that I had never heard of before.

In a pantoum the second and fourth lines of the first stanza become the first and third lines of the second stanza, and then so on for the rest of the poem, like voices calling from verse to verse.  My favourite example was “The Method” by J. D. McClatchy, which stretches the idea of the repeated lines, modifying them slightly to be almost the same, but not quite: perhaps modified, punctuated differently or simply sounding similar but completely different words. For example, the second line of the first stanza is “Seem to pee more often, eat“, which becomes “Sympathy, more often than not” as the first line of the second stanza.

By way of demonstration I tried to write a pantoum on the spot.  There were paper slips on the table, to allow you to write your order to take to the bar, and these became manuscript paper. The lines are very short, which is only fair as I was writing a five line poem on the fly, but I had also clearly forgotten the proper rules (I just rechecked now) as I have six-line stanzas, instead of four-line quatrains.  However, I did manage to get the last stanza to cycle round and use the unrepeated (1st, 3rd and 5th) lines of the first stanza, not bad for a two minute demo 🙂

Everything feels easy

Today looked like a good Tiree Ultra day, with 40 mile an hour winds (the odd gust at 50) and occasional shafts of sunshine between driving rain!

So buoyed by knowledge from three weeks ago that I could do it, I took my first run since the ultra.

My left leg is still feeling a little gammy, but with a 40 mph wind at my back I fair sailed along – until I turned round.  Progress on the return leg was … well suffice say I could have walked faster.

I have always avoided running in the rain, but after the ultra I knew I could do it and it wasn’t so bad.  I also had a new rain poof that I’d got for the ultra – good equipment really does help.

There is something liberating about that “it can’t be worse than …” feeling.

When I did the first Tiree Ultramarathon in 2014, it was a year after I’d walked around Wales.  If I got a pain whilst walking there was always the fear that it would be worse the next day, or that it would be the thing that stopped me entirely.

Just over 2/3 of the way round the 2014 ultra I began to get some pain in my right leg.  I’d pulled the Achilles tendon on that ankle a few years before, and so I was a little worried that it would go again.  But I thought, “only 10 miles to go, and it’s just one day. I don’t have to run again tomorrow and the next day; so what if I’m hobbling for a few weeks.

After walking 1000 miles day on day, a single day and mere 35 miles was suddenly less daunting.

Now, knowing I could endure a whole day running with horizontal rain stinging my cheeks, well what of a couple of miles in heavy drizzle and 50 mile an hour winds …

After Tiree Ultra 2017, everything feels easy.

Tiree Ultra 2017 – what a difference a week makes

Last Sunday I completed my third Tiree Ultamarathon … and definitely the wettest, windiest and boggiest!

However, this Sunday what a difference …

The ultra circuit flows the coast of Tiree taking in almost all of the beaches, but also includes some road sections as well as off-road grass sward and boggy moor. There is relatively little height gain, but Will Wright tries to organise the route to ‘make the most’ of the hills there are.

Previous years have been wonderful weather, light breeze and some sun, enough to be pleasant, but not enough to cause heat problems. However, the fates had been saving their fury, and this year the heavens opened and Odysseus let the western winds loose gathering water from the warm Atlantic and flinging it at us in horizontal sheets.

It was the first time I had every run in the rain so was, well maybe not a baptism of fire, but certainly a dramatic introduction., I had recently bought a waterproof for running in, but it sill had its label on as each wet August day, I thought “well maybe run on a brighter day”. Although everyone says that the right equipment helps, I sort of only half believed it – however, I was amazed at how even driving rain was not a problem.

I only run the Tiree ultra in September and sometimes the Tiree half marathon in May. I always mean to keep on running between, but then I forget, or I am too busy – so many excuses. So, in previous years I haven’t got round to any running until a month before the ultra doubling my distance each week – far from the recommended 10-15% a week increase! To be honest I’ve been very lucky to have not injured myself.

This year I decided to break my habit and be well prepared, so started a whole two months in advance. I wondered if this had been wise as I felt I’d peaked at the end of July and seemed to be going downhill ever since.  However, this year I am definitely hobbling less afterwards and I managed to run every inch of road and beach, with just a few walking sections over bog. This said, when the wind gusted mid to high thirty miles an hour in my face, I would almost certainly have walked faster than I ran.  Indeed on Gott Bay as I ran (very slowly) into the wind another runner was power walking just behind me sheltering in my lee.

One thing I noticed while running was a subtle change in psychology.  After about 10 miles, as pain and exhaustion kicked in, I was aware of myself occasionally wondering if there was any way I could bow out without losing too much face, and then not that many miles later I caught myself thinking “next year I’ll ….” – at that point I knew I was OK!  However, the exhaustion must still have been in my face at mile 17 as the marshal as we came off the beach at Balephetrish said, “you look as if you could do with a hug”.

This year two off-island friends, Albrecht and Alun, also came to Tiree for the Ultra, which was wonderful.  Being a good host I of course let them finish ahead of me by an hour or so 😉

Albrecht has already booked for next year, but not sure if Alun is convinced!

However, the weather can only be better.

 

 

running on the verge

In a week and half’s time I’ll be joining about 250 others on the Tiree Ultramarathon, running around the edge of Tiree, which is itself on the Atlantic edge of Scotland.   Some of this will be on beach and moor, but some along single track roads, where you often have to step onto the grassy verge as cars go by.

Running on the verge has its own challenges which I’m sure are shared by many rural areas as well as Tiree.  For those coming to the Tiree Ultra or running (or cycling) in rural areas, here’s my short guide to the hazards of the verge.

on narrow roads do stop – Some roads do have space for a car to pass a runner or cyclist, but it can be close especially if you are a little tired and ‘wandering’ a little as you run.  So usually best to stop … and you get a moments breather 😉

beware the ragged tarmac edge – It is tempting to just squeeze to the left and keep going, but the tarmac often peters out, this is worst of you are cycling as the wheel can slip off the road and get trapped in the furrow between tarmac ad grass (cyclists have ended up in hospital!), but you can also trip when running … and you don’t want to fall into the path of the car that is passing.

Tiree Fitness Facebook photos – verges are not the only road hazard

running on the verge – I know many will ignore this, but just don’t.  They seem wide, tamer than running on full off-road terrain, and well within the capabilities of a off-road bike.  However there are often drainage channels hidden by the long grass – these can be a foot or more deep and can be invisible.  Even when there isn’t a deep drainage channel running parallel to the road, there are often smaller drainage channels running outwards from the road; these are typically only a few inches deep, but just designed to trip you up.  The one possible exception is where someone has mown the verge outside their house, but even then be careful of the cross-channels as they often aren’t obvious even on mown grass.

stepping onto the verge – At the risk of sounding like your granny, still take care!  I have stepped off the road and, even looking down at the ground as I did so, my foot has disappeared into a channel and I’ve almost sprained my ankle … and that was standing still not running.  On the bike be even more careful, you stop, put your outer foot into what you believe to be grass and … on a bike there is little you can do apart from topple full head over heels … and, yes, I know because I have done it.

standing on the verge – Will it never stop!  Yep, even standing has it’s dangers.  On Tiree it is normal to wave to those passing, friend and stranger alike.  However, if you are a little tired twisting round can put you off balance.  Don’t feel embarrassed to put a hand on a fence post to keep you sure footed, better than stumbling back into the path of that nicely waving driver.

stepping off the verge – Do take a peek back down the road before stepping back onto the tarmac.  Tiree is windy and when the wind is coming from in front it is hard to hear cars from behind, as a car passes you it is easy to just step back, but often there is a second car driving in convoy, especially when the road has had a lot of obstacles (such as runners), so that cars catch up with one another.

… and then if you survive the verges

… there is just Dun Mor to climb …

why is the wind always against you? part 2 – side wind

In the first part of this two-part post, we saw that cycling into the wind takes far more additional effort than a tail wind saves.

However, Will Wright‘s original question, “why does it feel as if the wind is always against you?” was not just about head winds, but the feeling that when cycling around Tiree, while the angle of the wind is likely to be in all sorts of directions, it feels as though it is against you more than with you.

Is he right?

So in this post I’ll look at side winds, and in particular start with wind dead to the side, at 90 degrees to the road.

Clearly, a strong side wind will need some compensation, perhaps leaning slightly into the wind to balance, and on Tiree with gusty winds this may well cause the odd wobble.  However, I’ll take best case scenario and assume completely constant wind with no gusts.

There is a joke about the engineer, who, when asked a question about giraffes, begins, “let’s first assume a spherical giraffe”.  I’m not gong to make Will + bike spherical, but will assume that the air drag is similar in all directions.

Now my guess is that given the way Will is bent low over his handle-bars, he may well actually have a larger side-area to the wind than from in front.  Also I have no idea about the complex ways the moving spokes behave as the wind blows through them, although I am aware that a well-designed turbine absorbs a fair proportion of the wind, so would not be surprised if the wheels added a lot of side-drag too.

If the drag for a side wind is indeed bigger than to the front, then the following calculations will be worse; so effectively working with a perfectly cylindrical Will is going to be a best case!

To make calculations easy I’ll have the cyclist going at 20 miles an hour, with a 20 mph side wind also.

When you have two speeds at right angles, you can essentially ‘add them up’ as if they were sides of a triangle.  The resultant wind feels as if it is at 45 degrees, and approximately 30 mph (to be exact it is 20 x √2, so just over 28mph).

Recalling the squaring rule, the force is proportional to 30 squared, that is 900 units of force acting at 45 degrees.

In the same way as we add up the wind and bike speeds to get the apparent wind at 45 degrees, we can break this 900 unit force at 45 degree into a side force and a forward drag. Using the sides of the triangle rule, we get a side force and forward drag of around 600 units each.

For the side force I’ll just assume you lean into (and hope that you don’t fall off if the wind gusts!); so let’s just focus on the forward force against you.

If there were no side wind the force from the air drag would be due to the 20 mph bike speed alone, so would be (squaring rule again) 400 units.  The side wind has increased the force against you by 50%.  Remembering that more than three quarters of the energy you put into cycling is overcoming air drag, that is around 30% additional effort overall.

Turned into head speed, this is equivalent to the additional drag of cycling into a direct head wind of about 4 mph (I made a few approximations, the exact figure is 3.78 mph).

This feels utterly counterintuitive, that a pure side wind causes additional forward drag!  It perhaps feels even more counterintuitive if I tell you that in fact the wind needs to be about 10 degrees behind you, before it actually helps.

There are two ways to understand this.

The first is plain physics/maths.

For very small objects (around a 100th of a millimetre) the air drag is directly proportional to the speed (linear).  At this scale, when you redivide the force into its components ahead and to the side, they are exactly the same as if you look at the force for the side-wind and cycle speed independently.  So if you are a cyclist the size of an amoeba, side winds don’t feel like head winds … but then that is probably the least of your worries.

For ordinary sized objects, the squaring rule (quadratic drag) means that after you have combined the forces, squared them and then separated them out again, you get more than you started with!

The second way to look at it, which is not the full story, but not so far from what happens, is to consider the air just in front of you as you cycle.

You’ll know that cyclists often try to ride in each other’s slipstream to reduce drag, sometimes called ‘drafting’.

The lead cyclist is effectively dragging the air behind, and this helps the next cyclist, and that cyclist helps the one after.  In a race formation, this reduces the energy needed by the following riders by around a third.

In addition you also create a small area in front where the air is moving faster, almost like a little bubble of speed.  This is one of the reasons why even the lead cyclist gains from the followers, albeit much less (one site estimates 5%).  Now imagine adding the side wind; that lovely bubble of air is forever being blown away meaning you constantly have to speed up a new bubble of air in front.

I did the above calculations for an exact side wind at 90 degrees to make the sums easier. However, you can work out precisely how much additional force the wind causes for any wind direction, and hence how much additional power you need when cycling.

Here is a graph showing that additional power needed, ranging for a pure head wind on the right, to a pure tail wind on the left (all for 20 mph wind).  For the latter the additional force is negative – the wind is helping you. However, you can see that the breakeven point is abut 10 degrees behind a pure side wind (the green dashed line).  Also evident (depressingly) is that the area to the left – where the wind is making things worse, is a lot more than the area to the right, where it is helping.

… and if you aren’t depressed enough already, most of my assumptions were ‘best case’.  The bike almost certainly has more side drag than head drag; you will need to cycle slightly into a wind to avoid being blown across the road; and, as noted in the previous post, you will cycle more slowly into a head wind so spend more time with it.

So in answer to the question …

why does it feel as if the wind is always against you?

… because most of the time it is!

why is the wind always against you? part 1 – head and tail winds

Sometimes it feels like the wind is always against you.

Is it really?

I’ve just been out for a run.  It is not terribly windy today by Tiree standards, the Met Office reports the speed at 18mph from the north west, but it was enough to feel as I ran and certainly the gritted teeth of cyclists going past the window suggests is plenty windy for them.

As I was running I remembered a question that Will Wright once asked me, “why does it feel as if the wind is always against you?

Now Will competes in Iron Man events, and is behind Tiree Fitness, which organises island keep fit activities, and the annual Tiree 10k & half marathon and Ultra-Marathon (that I’m training for now).  In other words Will is in a different league to me … but still he feels the wind!

Will was asking about cycling rather than running, and I suspect that the main effect of a head wind for a runner is simply the way it knocks the breath out of you, rather than actual wind resistance.  That is, as most things in exercise, the full story is a mixture of physiology, psychology and physics.

For this post I’ll stick to the ‘easy’ cases when the wind is dead in front or behind you.  I’ll leave sidewinds to a second post as the physics for this is a little more complicated, and the answer somewhat more surprising.

In fact today I ran to and fro along the same road, although its angle to the wind varied.  For the purposes of this post I’ll imagine straightening it more, and having it face directly along the direction of the wind, so that running or cycling one way the wind is directly behind you and in the other the wind is directly in front.

running with the wind

To make the sums easier I’ll make the wind speed 15 mph and have me run at 5mph.

On the outward leg the wind is behind me.  I am running at 5mph, the wind is coming at 15mp, so if I had a little wind gauge as I ran it would register a 10mph tail wind.

When I turn into the wind I am now running at 5mph into a 15mph head wind, so the apparent wind speed for me is 20mph.

So half the time the wind is helping me to the tune of 10mph, half the time resisting me by 20mph, so surely that averages out as 5mph resistance for the whole journey, the same as if I was just running at 5mph on a  still day?

average apparent wind (?) = (  –10 * 4 miles  +  +20 * 4 miles ) / 8 miles = 5

Unfortunately wind resistance does not average quite like that!

Wind resistance increases with the square of your speed.  So a 10mph tail wind creates 100 units of force to help you, whereas a 20mph head wind resists you with 400 units of force, four times as much.  That is, it is like one person pushing you from behind for half the course, but four people holding you back on the other half.

It is this force, the squared speed, that it makes more sense to average

average resistance (wind) = (  –100 * 4 miles  +  +400 * 4 miles ) / 8 miles = 150

Compare this to the effects of running on a still day at 5mph.

average resistance (no wind) = 25  (5 squared)

The average wind resistance over the course is six times as much even though half the distance is into the wind and half the distance is away from it.

It really is harder!

In fact, for a runner, wind resistance (physics) is probably not the major effect on speed, and despite the wind my overall time was not significantly slower than on a still day.  The main effects of the wind are probably the ‘knocking the breath out of you’ feeling and the way the head wind affects your stride (physiology).  Of course both of these make you more aware of the times the wind is in your face and hence your perception of how long this is (psychology).

cycling hard

For a cyclist wind resistance is a far more significant issue1.  Think about Olympic sprinters who run upright compared with cyclists who bend low and even wear those Alien-like cycling helmets to reduce drag.

This is partly due to the different physical processes, for example, on bike on a still day, the bike will keep on going forward even if you don’t pedal, whereas if you don’t keep moving your legs while running you get nowhere.

It is also partly due to the different speeds.  Even Usain Bolt only manages a bit over 20mph and that for just 100 metres, and for long-distance runners this drops to around 12 mph.  Equivalent cycling events are twice as fast and even a moderately fit cyclist could compete with Usain Bolt.

So let’s imagine our Tiree cyclist, grimacing as they head into the wind.

I’m going to assume they are cycling at 15mph.

If it were a still day the air resistance would be entirely due to their own forward speed of 15mph, hence (squared remember) 225 units of force against them.

However, with a 15mph wind, when they are cycling with the wind there is no net air flow, the only effort needed to cycle is the internal resistance of chain and gears, and the rubber on the road.  In contrast, when cycling against the wind, total air resistance is equivalent to 30mph. Recalling the squaring rule, that is 900 units of resistance, 4 times as high as on a still day.

Even averaging with the easy leg, you have twice as much effort needed to overcome the air resistance.  No wonder it feels tough!

However, that is all assuming you keep a constant speed irrespective of the wind.  In practice you are likely to slow down against a head wind and speed up with a tail wind.  Let’s assume you slow down to 10mph in the head wind and manage a respectable 20mph with the wind behind you.

I’ll not do the force calculations as the numbers get a little less tidy, but crucially this means you spend twice as long doing the head wind leg as the tail wind leg.  Although you cycle the same distance with head and tail winds, you spend twice as long battling that head wind.  And I’ll bet with it feeling so tough, it seems like even longer!

End of an era

A few weeks ago, I gave a panel presentation at the ARMA conference in Liverpool — however, this was my last official duty with a Talis hat on.

Talis is a small employee-owned company, and maintaining a research strand has been far sighted, but unusual. After a period focusing more in the development of new products, Talis is shifting to a phase when every resource should be focused on delivery … and hence long-term research, and my own role in the company, has had to cease.

Talis has been a wonderful place to work over the past seven years, both the individuals there, but also, and crucially important, the company atmosphere, which combines the excitement of a start-up, with real care and sense of community.   So if you spot posts advertised there, it is a great place to be.

Talis was my principal regular income, as my academic role at Birmingham has only been 20%, so long-term I need to think about whether I should increase again my academic time, or do other things. I have been very fortunate never having previously had a time without regular income, so this is a new experience for me, although, of course, common.

Over the past few years, I have kept some time ‘unwaged’ for other projects (such as walking round Wales!) and occasional consultancy, and my to do list is far from empty, so this summer and autumn I am intending to spend more time writing (yes TouchIT will be finished, and editing the Alan Walks Wales blog into a book), picking up some of the many half-finished coding projects, and doing videoing for Interaction Design Foundation
