Back for 2019 is the California DIRT MTB Series, one of YBONC Foundation’s fundraisers to support programs for Nevada County school bike clubs. We have been selected again by USA Cycling to host the 2019 California MTB XC State Championship as a series. There will be a cash purse to the Pro classes. Cash prizes will vary depending on class size/participation. Podium medals and a fee bundle package if you know you will race all race dates.
