Your registration for the Lost and Found Gravel Festival supports Sierra Buttes Trail Stewardship's Lost Sierra Route, connecting 15 mountain communities to promote economic prosperity through
recreation.
The Lost & Found course features a perfect blend of pavement, dirt road, gravel road, and historic railroad grade. Racers must choose their weapon wisely (Gravel Bike, Cross Bike, or Mountain Bike).
All routes start in Portola at the City Park and focus on riding up into the surrounding mountains and through some of the most beautiful and empty alpine valleys, California has to offer.
Participants can choose to race or simply ride the route and take advantage of the quality aid stations. Racers and riders from around the world will be invited to lose themselves and find this two-wheeled paradise.
Saturday ride and post-event fun in Portola with food, beer, live music, and dancing - the way we like to do it! Come join us for a great weekend in the Lost Sierra.
