About the USAC Categories
In USAC mountain bike licensing, a racer can choose which category they want to race in.  So anyone can race Cat 1 with the fast guys if they want to. Cat 1 is the experienced category; Cat 2 is intermediate, and Cat 3 novice.  In the XC Series, Cat 1/2 race 34-36 miles and the Cat 3 race 24-26 miles.  For the Marathon Discipline, all categories race the same distance.  Juniors race an age appropriate distance in the Junior XC categories. For Breckenridge all Categories race together. Cat 2 and 3 can purchase an annual or $10 one-day license, whereas a Cat 1 must purchase an annual or $25 one-day (Cat 1 one-day license is called an “experienced one-day” and must be purchased on-line only through USAC and not available to purchase through bikereg like the Cat 2 and 3 one-day fee).

No refunds due to acts of God, or other personal scheduling issues. However, we can facilitate a registration transfer to another.
