Keyesville Classic

This is slightly south of NorCal, but since it's such a large race/festival, I thought it deserved a mention:

For 22 years, the Keyesville Classic has drawn casual riders , pro mountain bike racers and their friends and families to participate in a fun-filled weekend of bike-related events and activities. From the entertaining Vintage class, Observed Trials, and popular Kids' Race, to the highly challenging Bionicon All-Mountain Stage Race where riders tackle the Short Track, Cross-Country and Downhill courses all on the same bike, the Keyesville Classic has something for everyone, riders and spectators alike.

Every year, the Keyesville Classic brings together local riders, advocacy groups and racers from all over the West Coast to raise awareness and generate contributions for trail stewardship in the Kern River Valley, and southern California. Up until last year, the Southern Sierra Fat Tire Association (SSFTA) in Bakersfield ran the event, and at one point it was the largest race on the west coast. Bionicon now directs the event with support from the SSFTA from their newly opened headquarters in Kernville.

This year's Keyesville Classic will be March 19th - 21st in Keyesville, CA. Keyesville is just east of Bakersfield, CA and about 3 hours from Fresno, CA [MAP].
