Never try something new on race day.
That's one of the biggest pieces of advice that athletes are given. And it's a good one. So, I'll likely be ignoring it spectacularly on Saturday. Never mind this race could take 8 hours if I have a bad time of the hills so if something is not right, it's going to be a long day of not right to get through.
I'm undecided on the shoes at the moment and I have a bit too much choice on that front, but I have ruled out a bunch immediately and there's a short-list of 4 left. I won't get to change them during the race so it is quite a key choice. The socks I can carry a spare pair with me, but the plan is either thick merino Smartwool ones or the brand new Drymax ones I just bought which claim to keep wetness to a minimum compared with many others.
Everything else is tried and tested and should be fine - especially hydration which I think I have nailed now.
No parkrun for me on Saturday as my race starts at 08:15, but I'll be thinking of all those thousands of parkrunners at 9am and maybe one of them will be thinking of me.
