In 2005 (in WI) there were three classes for CX. Class A, B & C with A class being "elite" and C class being "beginner". This year the classes for women have now changed to Cat 1/2, Cat 3, Cat 4 with Cat 1/2 being "elite" and Cat 4 being "beginner".
When you buy a NORBA sport license, your CX class will automatically be Cat 4. But you will typically see the sport mountain bikers race Cat 3 for CX (here in WI). So that is why I chose to upgrade right away. I thought it would be a more appropriate place to start....and it was. Though I really need to work on all the techniques that I learned as well as do some high intensity workouts to really gear up for this type of racing. It should make for a really fun and educational fall season of racing bikes.
Yup, I'd have to agree with you!
