I definitely learned some hard lessons about kit requirements in TP100.
I would definitely have a goretex jacket in my pack if I did this event again.
I don't think I would use goretex shoes, because the water gets in over the top, and then they just make matters worse.
Above all, it was people who took care of their core body area who were least effected by the weather conditions.
I would say that the conditions underfoot in the last 20 miles, definitely harmed the finishing times of many competitors, so we might well be able to do better next time round.
