Thinking about signing up for an XC race this weekend, the Root 66 at Grafton ponds. I haven't raced XC in probably 15 years (did miserable then) but I ride somewhat regularly up to 12 miles, usually around 6. What category should I go in? Cat 3 is 9 miles, cat 2 is 13.5. I previously raced cat2 DH and got my ass handed to me by both sandbaggers and non....but I don't want to take anything from beginners.
