As most of you know, we will behaving a STXC or Short Track Cross Country race at Scott County Park this year. I have had a number of inquiries about this format. The best definition I have found is: Mountain Bike Short Track race ~ [MTB shôrt trak ras]
a mountain bike race similar to a criterium where riders do multiple laps on a short 3-5 min course.
Very fast and fun!
