I am planning to make the trip from Canada to California this summer. My boyfriend has entered into the Downieville Classic XC Race. I would also like to enter, but I am not sure how difficult or technical the trail is. I am relatively new to XC mountain biking and do not know whether or not I will be able to finish the race. I have a Kona Caldera hardtail with 4" travel. I would like to know what I am getting myself into before I enter the race. Is this race too hard for an amateur? Thanks!
