100 mile mntn bike race--who's done one?

[Anelia]

I've done a couple 100's and in addition to properly training your body for pounding away the miles, I think the other, almost equally important, thing to figure out and "train" for is your food and drink consumption pacing. So I'd say practice this too! On long rides think about what you can continue to eat, what's working, what's not etc etc. Hope this is helpful - and good luck!

Sambike, thank you very much for this reminder. This is something every experienced rider knows about BUT we sometimes make stupid mistakes overlooking thing that are "by default".
I suggest that we make a list of important things which we should not forget. I'm in with:
1. butt cream
2. electrolytes
3. to be added later
