Oliver has been a member of the Camino Coaching programme for only 5 months and within that period he has already gone from 50KM (Camino Lea Valley) to 50 mile trail (Jersey Round the Rock) to his first 100KM.
With wonderful passion and a desire to set his running bar high Oliver found himself with big targets for last weeks Thames Path 100km (his A-goal target would have won the event)
Oliver wrote about his experiences on his brilliant Reddit page - it is such a candid, raw, funny-at-times report that is rich in ideas and self-experimentation that we asked Oliver if he would kindly let us share it with our Camino audience.
Please let us know what you think.

Did my first 100km. Asked this sub if I was capable of ludicrously fast times. Was informed I would not be. Revised goals down but they were still far too ambitious. Faded very badly and at the 3/4 point had a genuine crisis of the soul. Rallied just enough to get to the finish. Learned a lot about myself as a runner and a person. Deeply humbled by the experience, but also grateful for it.
M34 who took up running in 2018 to lose weight. I did my first marathon in 2019. In 2020 I had a breakthrough year and hit a lot of PBs including two sub-3 marathons, sub-37 10K and a sub-18 5K. For a long time I had felt fat and unathletic and I really came to love running; it gave me a feeling of achievement and pride in my body. As I would come to discover, I had become maybe too dependent on this feeling of progress.
Unfortunately I picked up a case of plantar fasciitis in autumn 2020 which disrupted my training until April this year. During lockdown I decided that when I could go outside again, I would spend as much time in nature and the outdoors as possible. What better way than trail ultras.
I built back to weekly mileage of 80-90km with peaks of 100+. I ran a couple of flat 50Ks in June and a c. 75km trail race with 1500m elevation in July. The goal with these had been to finish strong but with an eye to further training. Thames Path would be my first 100km but also my A race for the autumn, and given it was a very flat route, and I was used to planning and executing races well, I was feeling ambitious and decided to go for sub-10hrs.
My last 5 weeks of training. Weekly totals plus highlights:
97km (including the 75km race in c. 8h 20m. I aggravated an ankle problem so started doing some recovery runs on elliptical to take pressure off it)
30km (+ 1hr elliptical) - recovery week
95km (+ 30 mins elliptical), including a fast HM B race (1:27)
106km (+ 2hrs elliptical), finished the week with a marathon in 3:40, most of it at sub 5:00/km pace with some warm up and cool down miles.
last week: 78km (start of taper)
I readied my kit and drop bag contents the night before using an extensive pre-race routine written on my phone. I refine and improve the routine every time I race and find it helpful for staying organised. I will add a comment with my kit list if helpful
Shoes: I used a pair of Hoka One One Clifton 7s which I had already done one training marathon in. In training, I run with a pair of insoles to relieve pressure on my plantar fascia and posterior tibial tendon. Over shorter races I use Algeos rear-foot wedges to help control my foot from rolling inward but without the weight of a heavy plastic insole. I had agonised over whether to use these for this ultra, thinking the less weight the better over long distances. Eventually I decided not to risk my tendons for the sake of a few grams, and go with the plastic insole. I think it was the right call.
Vest: I ran with a cheap Aoinijie 18L vest which I think is excellent for the price, plus 2 x 600ml bottles with straws from the same brand (I find camelbacks too heavy and difficult to refill).
I spent the preceding two days carb loading by eating more bread and rice and avoiding fats. I got to bed at 11pm and slept soundly. The alarm went off at 4:30am for a 6:50 race start. I ate a breakfast of a cereal bar and porridge. I drank two coffees to stimulate a movement, which I thought worked (in hindsight this was a mistake...)
I knew that the chafing, blistering and gut problems that might irritate me in a marathon could blow up into race-ending issues over longer distances. So I used a lot of Vaseline in every crevice and threw a fair amount of 2Toms Blistershield powder in my socks and back up socks (although I had to empty some out as it made little lumps in them). I took a pre-emptive Imodium and stored more in my vest for the halfway point. I wore knee high compression socks with another pair of shin compression gear over the top of those. And although it would be a cloudy day in England, I still threw factor 50 sunblock on, just in case.
I took a cab to the start line which cost a fortune but I wasn't about to walk to the bus given the amount of time I would be on my feet that day. The race set off from a small park in West London next to the Thames. The event was mainly for walkers but it also catered to runners who had an early start time. The weather was cool and clear in the morning, and the day was set to be cloudy albeit a little hotter than normal.
My hydration strategy was to drink one of my 600ml bottles between aid stations which were spaced every 10 to 14km.
My nutrition strategy was to get 250 calories an hour from a combination of solid food at checkpoints with a Gu gel in between; I knew from experience that a diet of 100% gels would destroy my insides after 50km, but with plenty of Imodium and a mix of foods, I would be ok. I had some old SIS gels I brought with me just in case I needed something isotonic (to combat dehydration) or caffeine free to give my guts a rest. My parents very kindly followed me in their car between checkpoints throughout the day to provide support, and they also carried a bag of Tailwind. I threw a couple of scoops into one of the 600ml bottles for an easy source of carbs and electrolytes, and to provide another option in case my GI tract began to rebel.
0 - 25km The race was very well organised with an easy check in and bag drop, and we started bang on time. I settled into a comfortable rhythm at around 5:45/km, firmly on 10 hour pace, as we began to move west from the centre of town towards the sights of West London (Kew Gardens and Hampton Court Palace). I said hello to and chatted with a few competitors and told them my target time, which I would begin to regret later in the race. One runner kept overtaking me, but I would pass him when he took walking breaks; he told me this was because he had a sensitive gut and walking made it easier to digest. I would be taking this advice myself later in the day.
Unfortunately I managed to miss a turning early on and cut around 500m of the course. Wrong turns later in the day would more than make up for this distance but it was a bad early omen. The path occasionally turned away from the river and wound back and forth between the north and south banks of the Thames. More than once I would have to ask passers by if they had seen route markers up ahead. I twice had to call out to another runner ahead of me that he had missed a turn and was off course.
Aid stations had plenty of chocolate, bananas and energy drinks which I stocked up on at every chance. I remembered reading, "An ultramarathon is an eating competition with running thrown in" on this sub and was determined not to let this do me in.
The Thames Path runs through towns, villages and near empty countryside, much of it flat and green. In the morning we passed many rowers training, and later in the day there were families playing and picnicking by the water, and after lunch a few merry bands enjoying drinks on boats. There was the occasional turn onto dual carriageways or through uninspiring architecture, but for the most part it was a really lovely tour. The organisers had marked every kilometre and as the event progressed, passers by, walkers and other runners on the path offered plenty of encouragement which was so great to receive.
At 23km, my guts began to unexpectedly grumble, and I realised I might not make the aid station. A wise man once said, "Eat before you are hungry, drink before you are thirsty, and shit before you shit yourself." I had to take an unfortunate trip to a bush and while I had packed toilet roll it was a really bad sign. I took another Imodium earlier than planned and hoped it would get things under control.
25 - 50km
I left the 25km feeling ok but at 30km I began to realise fatigue was setting in earlier than I had expected. I wasn't sure if this was normal tiredness, or the start of a breakdown. My heart rate still seemed under control, so I decided to take the high risk approach and keep pushing at this pace.
I passed the marathon split in around 4:05 and the 50k in around 4:50. However, I had to admit to myself at the 50km point that things were not going well. At that checkpoint I admitted to my parents that I was probably going to reach the next checkpoints later than planned.
At 50km I changed my hat but elected not to change any other clothes or shoes (it didn't seem to make a difference to me). I did reapply sunscreen. I also had to make another toilet stop and noticed GI discomfort starting to creep in. At this point I was still rushing through the aid stations, as much out of frustration as anything else as I knew even sub-11 would be challenging.
50 - 75km
I left the aid station and after a few token miles trying to keep my splits to 6:00/km, on the edge of a 10:15-10:30 final time, once aid station stops are factored in. But the pace slipped very easily to around 6:30/km. At this point I was in around 8th place. The sun had came out and the day felt much hotter and more humid than we had expected. I began running with a women who had caught up to me. An aid station volunteer told her she was the female race lead, and we were currently in the top 15. We were both surprised that the field was so slow today - previous years had been much faster - and we mused on what the reason might be.
By this point I had come to recognise one or two other runners and I recall complaining to them about nausea. Solid food was not going down as easily and the list of things I could eat was dwindling (it would soon reach zero). I went from eating chocolate and bananas at aid stations to drinking energy drinks and 50/50 coke and water mix.
I made it to the 3/4 point still technically on sub-11hr pace, but by this time I had to accept that I was really struggling and barely able to run. I had to apply a pre-emptive blister plaster to my heel, where my sock had worn through, but that was the least of my worries.
I found myself very nauseous and unable to eat anything solid. My mother ignored the rules telling spectators to stay out of the rest areas and came to tell me I looked really ill. She had never understood why I did this sport. "It's fine, this is normal", I said, but I didn't believe it myself. She suggested I give up if I had to, that if I continued I only walk, and that if I needed to drop out between rest areas they could pick me up. It came from a place of love but it was very difficult to hear. I took another toilet break before I left - I had taken three Imodium tabs by this point and didn't want to take more for fear of doing myself damage, but still my GI tract was rebelling.
75 - 100km
I left the 75K check point in a state of dread. At this point I could barely run at 8:00/km. Before this day, I would not have believed it was possible to go this slowly and still technically be running. My gait was a strange shuffle; I felt like an 80 year-old version of myself.
At 80km, I realised that I had blown up so badly, I might have to walk the next 20km to reach the finish. If you blow up in a marathon and have to jog in the final four miles, that's bad. But if you have to jog in the last quarter of an ultramarathon, you might be walking for four hours. That's a long time to be left licking one's wounds.
Worse, I was struggling to take in even water without waves of nausea, let alone carbs. Could I even keep my body going for four hours without more food and calories? It would be worse than a waste to keep going at a snail's pace for two more hours, just to hit a total wall or collapse at 90K and to have to DNF anyway.
I began to suffer a bit of a mental crisis and became quite emotional. I realised that almost every time I had tried something new in running it had gone well; even when I failed to hit a target, I would PB. This was the first time I was facing dreaded, abject, public failure. I would have to tell my family, friends and colleagues that I had failed to finish the thing I had been talking about for weeks. I realised that I had come to depend on running to make me feel strong and successful and worthy in the eyes of others who had praised my sudden turn from fat guy to amateur endurance athlete. And here I was discovering that I was the same weak person, who struggled in every domain of life; relationships, careers, everything. I was still full of fear and doubt and I didn't even have my mediocre amateur physical achievements to cover up for it.
I had phone signal and decided to call my partner. I voiced many of these fears to her and will admit that there were a few tears. She gave me a pep talk and after ten mins of chatting I began to feel better.
Things that helped in this moment:
An article I read about how to recover from "bonking" (which means something very different here in the UK, but anyway). I can't find it now but it contained a sentence along the lines of, "In the worst depths of this crisis, you must have faith that you can recover. You will feel ok again and finish, and maybe even finish strong." I knew my issues went beyond nutrition - my muscles had stopped working - but I trusted the author, an experienced professional, that if I kept going, things might improve.
Having a new goal. No I wouldn't hit my time goals, but "Don't DNF" became a goal worth suffering for.
Focussing on the positives. I shared some of my woes with an aid station volunteer, who said in passing: "Of all the routes in the world to be stuck walking, this is a good one." And he was right. It was no longer that hot as late afternoon passed into evening. Children were playing by the river. Cows congregated in fields. Deer wandered on country estates. People on boats waved to us on the river bank. Bits of historic England popped up every few minutes. It was a nice place to be.
I thought about Yuki Kawauchi at the Boston Marathon in 2018. Many elites dropped out in torrential rain but he kept going because he shows up to and finishes every race, and because of that he won a major title. As long as you keep showing up, you never know what might happen. I thought of a few other greats and let their examples inspire me.
Incredibly, as I kept going, things got better. My legs were restored to the point where I could coax a few mins of 7:30/km pace running out of them, followed by a couple of minutes walking. That doesn't seem like much but my watch told me it would be enough to get me a sub-12 result which would be the cherry on top of finishing. And while I was passed a few times between 80 and 90km, from 90km I didn't see anyone coming up behind me; the closer I got to the finish, the more likely it would become that I would get a result in the top 20, which became an additional incentive to keep going.
I still couldn't eat anything and was now on the verge of vomiting. Even the Tailwind was making me nauseous. By 90km I could only sip a little water at a time. I was reduced to swirling drinks in my mouth and spitting them out. But it helped, and I figured it was enough to get me to the finish.
With 5km to go, I was just about able to sustain a gentle trot. I crossed the finish before it got dark and hugged my parents. I was very quickly overcome with a case of the shakes and bad chills. I wrapped up warm and drank hot, sugary tea. I failed to stretch or really do anything except clamber in the car and sleep on the way home; I would not recommend this.
What I learned
Most importantly, I learned my limits as a person. In the depths of my crisis at 75K, I realised I had pushed so hard at the start of the race because I needed this result to be special, to make up for other perceived failings in my life. In that moment by the riverbank by myself, my legs were gone and I couldn't run at all. I had nothing left but failure, and I was faced with the fact that I am riddled with weakness. And it was fine. I learned to accept that about myself and be at peace. The next time I go for a run or enter a race I will still be ambitious and excited about what I can achieve, but I don't think I will be doing it to feed my fragile pride. Maybe I can do it with greater modesty, humility and ultimately a greater sense of joy.
I understand now what my different levels of exhaustion are. I know that if I feel a certain way at 30km it's time to slow down.
I don't need to eat 250 calories an hour. I haven't hit the wall from poor nutrition in two years. The bigger risk is clearly nausea and dehydration. I think I overate both in the run up to the race and in the first half and was punished for it.
I also learned that time works differently in an ultra. A few extra mins of walking here and there, or a few mins extra at an aid station getting ready for the next leg (applying lubricant, taking care of blisters, digesting, catching up with supporters, etc), can make you much faster in the long run.
I learned a lot about the limits of my GI tract. No caffeine except maybe in the final couple of hours of a longer race. I sabotaged myself badly by drinking coffee and using caffeinated gels. For me, it's fine in a three hour marathon. Anything longer and it's just laying dynamite which will blow up later.
An easy week off to let tendons recover with maybe a few slow miles here and there. I am tempted to train for shorter distances (5, 10 and half marathons) before taking a run at Boston, assuming my qualifier from last year gets me in once I have graduated into the next age bracket.
Thank you to the running community on this sub and beyond for all the inspiration and learning. You tried to warn me but I had to learn this lesson the hard way. Although I feel humbled and a little bit sad I didn't post a better time, I think this experience has made me a wiser runner and person in the long run.
