Where Your Money Goes

Events are one of several ways the 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 Grinduro - 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. Thanks for your continued support and participation, and see you trailside!
