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

[TrekJeni]

My friend wants me to race a 100 mile mountain bike race with her this coming spring. Sounds like fun to me! But I have no idea how to train for one on my limited schedule. And I have no idea what to expect! Just wondering if anyone on the forum has raced one before. I would like to hear your experiences.

Thanks!

Lumberjack rocks! It's beautiful and the terrain is varied. What I did to prepare was ride a lot of road miles because we had such a wet spring.
