Where Your Money Goes
Participating in this 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.
The Lost and Found supports the The Lost Sierra Route part of the Sierra Buttes Trail Stewardship's Connected Communities Project. By raising donations to build the The Lost Sierra Route, you will help a region recover from devastating wildfires and economic hardship through the creation of this 600+ mile multiuse trail. The Route will connect 15 mountain communities to promote economic prosperity through recreation - a $887 billion industry - and create new jobs in the Lost Sierra region.
Thanks for your continued support and participation, and see you trailside!
Watch "A Trail for Everyone" a short film about Connected Communities, the proposed “Lost Sierra Route” and the positive impact of linking 15 California mountain communities through trails. Funds raised by the Lost and Found support this project.
