I'm in pretty decent shape and am considering doing a mountain bike race. I've got an old Trek Y-11 that my buddy gave me years ago. She's in good shape I made some upgrades but no carbon fiber wheels etc. Am I going to be made a fool of at the start line? Are Mtn bike races are a little more laid back than road races. I'm thinking of registering in the Cat 1 18 miler. I just took her for a hilly 48 miler this past tues at an easyish pace and averaged around 12 mph. I have no intentions of winning just looking to try something new and have a good time(suffering). Can I register in any category even though I've never raced before?
Thanks in advance.
