Mountaing bike racing is simply a competitive form of mountain biking. Simple rules, you have to finish on the same bike you started with, you can't have any outside help with repairs, don't cut the course, and most of all, have a blast! A great sport to compete in, there is a real sense of camraderie after you get muddy and bloody with a bunch of fellow bike nuts.

They have races all over, at all times of the year... they've even started having 24 hour relay races.
