Hey wicked, go for it.There are usually a number of classes to run in ( novice, intermediate, hot shoe, pro) whatever. Don't worry about the guy's around you. If you're in the right class everybody is going very close to the same speed and the fast guys will find their way around you. Usually the organizers ask that passing only done on straights for the lower classes. It's a great way to find your limits in a safe environment. Have fun.
