Mountain Bike Race

This evening I rode in my first ever mounatin bike race...needless to say I was not as successful as I wass this morning! I had real difficulties working out how to use my gears...and my chain came off at one stage! but I apart from that I think I did OK...However I have a lot of catching up to do in tomorrow's race! I have to win by about 15mins to win the weekend's races over all. I think it is possible as tomorrow is an 18km mountain race (my speciality).
