I've raced MTB endurance events, 24 hour events, cross country, cyclo-cross, road, but never MTB short track. If it's anything like CX, I know I am going to get worked but I'm pretty excited to try it. Details here.
Let me start the anti trash talking now by stating that on Friday, I will be doing the Fast Friday version of RAWROD, driving home late Friday night, getting up Saturday morning and racing. I can't wait to hurt myself two days in a row with two completely different events.
