Event Cancelation Insurance Included
SBTS has opted into a third party Event Cancellation Policy program, administered by Adventure Advocates, that will refund registration fees should this event be canceled for a qualified reason. 2.2% of all registration fees pay for this insurance. A wildfire prohibiting race course/venue access is among qualified reasons listed in the policy. It is necessary to opt into this program as we have seen other events have to be canceled very close to the event date due to wildfire impacts. While we hope to never be in that situation, we wish to protect both our participants and SBTS by enrolling in this program. Should this event occur, refunds of race registration fees will be sent by Adventure Advocates to all registered racers directly to the payment form used at registration checkout. See full program disclaimer here.

We highly recommend you also purchase the Allianz Participant Registration Insurance during checkout in BikeReg, which may cover you for unforeseen circumstances that cause you to miss the event.

Where Your Money Goes

Events are one of several ways the Sierra Buttes Trail Stewardship (SBTS) raises funds for making trail magic happen in the Lost Sierra.

If you've ever ridden the iconic trails of Downieville, the Lakes Basin and Mills Peak near Graeagle, or our newest creation, Mount Hough Trail in Quincy, you know how much time and effort goes into making these world-class trails.

Our three events - the Lost and Found Gravel Grinder, the Downieville Classic and Mountains to Meadows - are not only filled with challenges, adventure, camaraderie and a huge post-event celebration, but part of your entry fee also helps employ local Plumas and Sierra County residents full-time, working to establish a more sustainable recreation-based economy.

Participating in an SBTS event is more than just riding your bike and having a good time; it's helping create some of the best trails in America while helping communities in the Lost Sierra thrive, keeping the dream of wholesome mountain living alive and well.
