**Update 3/14/18: Race #1 on the Hoot Trail is CANCELLED.**

Due to late winter low snow levels we are being forced to make last minute decisions. Info on new CA Series opening race upcoming. Please check Facebook for most up to the minute changes. Thank you for your understanding!

We have a new event name, “California DIRT MTB Series”.  And yes, Synergy Race Timing will be chip timing our series!  Another bonus, we have been selected again by USA Cycling to host the 2018 California MTB XC State Championship as a series.  Lots of time applying for what it takes to put on a series is happening such as permits, insurance, outreach to sponsors and volunteers, etc.  It all comes together on race day for our racers.  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.

No one wishes to be preached to so please view this as one mountain bike community member to another. To continue the advancement of our sport, both in creating more trails to ride and more races on those trails, we all need to make an effort to care for those environments. The vultures are always waiting for us to slip up and take away our dirt. Please don’t give them a reason!!!

  • Carpool!
  • Pack-it-in and pack-it-out – and please, please use bathrooms or your own system – not on Mother Nature
  • Be prepared and bring your own water and supplies
  • Help keep our trails primo…Ride it, Don’t Slide It
  • Most importantly, race hard but ride friendly especially when encountering folks in other sports/activities

The CA Dirt MTB Series was born from the Nevada City Dirt Classic. The event originally began with the owners of Extreme Outfitters Bicycles, Charlie and Kim Cuisinot in the early 2000’s and YBONC resurrected it. This is a fundraiser series, benefiting Youth Bicyclists of Nevada County Foundation Programs for school bike club youths. Thank you to the Tahoe N.F. for permitting us this recreational event and at the same time helping us to support our mission.
