After pulling out of the first two Centurion 50 milers I finally felt fit enough to tackle my second ever 50 mile race, the CW50 (Chiltern Wonderland 50). Training this year has been pretty poor due to the never ending injury and only in May things started looking normal or at least bearable for my shin and ankle. Since then I tried to get back into running seriously. I paced Manu for the last 55k in his epic SDW100 in June, I then ran the NDW Marathon and Chiltern Challenge 50k Ultra in July. In August I had my ass handed to me while pacing Davide on the NDW100 and again racing the Intro to Ultra Peak District 50k. Coming into September I was feeling pretty good. I did some long weeks, culminating with a 40k Saturday followed by a 30k Sunday two weeks before the CW50 that gave me confidence. Especially the run I did on Saturday where I tried to keep my heart rate very low and see how I felt. It felt good and after 30k I was fresh and accelerated happily.
I therefore decided to base my effort on the CW50 on my heart rate. I was going to try and keep it under 140bpm for at least the first 50k and then see if I could accelerate a bit towards the end. Instead of starting too fast and then crawl at the end like I usually do.
Last year I did my first 50 miler in exactly 10 hours (NDW50). At the time I was a lot fitter than this year, but a lot less experienced, so the plan was to try to finish at least under 10 hours.
I love the Chiltern Hills and as this race does not follow any particular national trail we were promised an especially beautiful route and we were not disappointed. Those hills are fantastic and the whole race went up and down beautiful hills, many woodlands and very few boring road or open fields. The views when popping out of the woods were some of the best you can get in the British countryside and definitely kept your mind away from the effort at hand.
As planned I started slow, keeping an eye on my heart rate. The first 5k were mostly flat on the river side so I needed to stop myself from going faster.
The first real hill came and to keep the heart low I started walking bits of it, eating the first gel of the day. That was basically what I did the whole race, as soon as I felt it was too much effort going uphill I was walking. Walking with intent, but not killing myself. At the same time if the trail was flat or downhill I ran it. No excuses this time. In previous races I always misjudged the pace and ended up having to walk some bits on the flats too towards the end. Not this time. I am very pleased with my performance. I never felt like I wanted to kick myself for starting the race and loved every second of it.
At the first aid station I basically did not stop, just grabbed a cookie and kept going. I was feeling a bit cold and I did not want to slow down too much.
I ran a big chunk of the race between the first aid station and the second with a very nice guy and we chatted away. Before we knew it we were at Bix’s aid station, 18 miles done, eating watermelon and feeling great.
The real hills started there and I was glad I saved some energy. The steepest one was the one going up to a windmill. It was so steep you could not even walk it up in a straight line.
I stuck to my tactic of keeping the effort level, eat every 40 minutes or so and just enjoy the day. I even started overtaking people and at the halfway aid station at Ibstone I had one of the best cake/cookie/whatever it was. I was not cold anymore and I was actually running out of water before arriving to the next aid station which was a bit of a problem. Especially as I was using Tailwind this time so my liquids were even more important towards the end of the race, when I have trouble eating gels.
I had promised myself as a reward/incentive that I would have started listening to music after 50k. I waited a bit longer and only put some music on after the Swyncombe aid station. It was probably the best moment of the race. I realised my legs where still almost as new. I was not tired at all, I was enjoying the day out and I was just moving forward, almost without thinking about it. The music made it even more amazing and I found myself singing.
I realised I had paced it right when I started overtaking a lot of people. I think I passed almost 10 runners at the golf club in Nuffield. I was pretty excited there as I had run there twice already and I knew how much fun was running down to Grims Ditch.
I got there pretty broken up by the downhill, but I was 41 miles in, only 9 left to go! A couple more watermelon slices at the aid station and I was off.
It was hard to keep running at that point but the excitement kept me going. The last 3 kms I just let myself go, no point in saving energy anymore. When I entered Goring village I felt supersonic, I even high fived some kids. I had done it and I did not suffer too much. 9 hours and 22 minutes. Not amazingly fast but much better than I expected. Now I know that on a good day, when I have no stomach issue, no injuries etc I can run at that pace without too much pain. Now all I have to find out is how much faster I should go and still not crawl too much at the end. That’s what I will find out in November at the WW50. I cannot wait.
As all of Centurion’s events it was perfectly organised, the aid station volunteers were amazing, the route was perfect and the Chiltern hills are my new favourite place.
