Running

Mental strength course... I can't imagine anything worse than running laps of Dorney - at least its flat! I'm sure I've mentioned it but I had a coach who used to make do 180-210km rides on a 30km circuit going past my front door every lap. He wanted to give me every possible opportunity to give up and go home - his rational(?e) being that if I could keep going after 5, 6 or 7 hours of whizzing past my bed and a nice warm shower, then I'd have no problem in races. Out and back courses are easy - if you stop you don't get home.

I think its quite nice knowing where you are, knowing there are drinks and a crowd of people cheering you on at a specific point is a bonus.

I'd probably consider doing a marathon there tbh might need someone to tell me what lap I was on though!
