About This Event

The Lost and Found Gravel Festival celebrates gravel cycling in California’s Sierra Nevada Mountains, taking place in the Lost Sierra’s expansive alpine valleys. This mixed-surface event blends pavement, dirt roads, gravel roads, and historic railroad grades through some of the state’s most stunning mountain terrain.

The festival offers three distinct routes, each designed for different rider types and ambitions. The Full Bull stretches 96 miles with 7,688 feet of elevation gain across 80% dirt trails, designed for serious racers and riders seeking a genuine challenge. The Mid Moo covers 64 miles with 4,928 feet of climbing and 70% dirt surfaces, perfect for adventure-minded cyclists who want substantial distance with scenic rewards. The Half Calf provides a more social 40-mile experience with 2,503 feet of elevation gain and 35% gravel, ideal for riders prioritizing good times over grinding watts.

Both longer routes climb toward Smith Peak early, rewarding the effort with excellent views of Lake Davis. New for 2026, organizers have removed the notoriously rugged rocky descent from previous years while maintaining the course’s scenic focus and challenging character.

The Sierra terrain demands respect and proper equipment. Organizers recommend at least 40mm tires for cyclocross bikes, suggesting models like WTB Raddler, Riddler, or Resolute. A rigid mountain bike with 2.0 tires works well too, especially given the rocks and rain ruts that cross dirt road sections throughout the course.

Beyond the riding, the festival creates a genuine mountain celebration. The weekend kicks off with a welcome party featuring live music and refreshments, continues through race day with staggered start times, and concludes with post-ride recovery including meals, awards, and extended live music performances. Free kids’ races add family appeal to the evening festivities.

As part of the global Gravel Earth Series, the event connects local mountain culture with international gravel racing, while supporting Sierra Buttes Trail Stewardship’s ongoing trail maintenance and community development work in the region.

Sierra Buttes Trail Stewardship is a non-profit organization that builds sustainable communities through creating and maintaining multi-use trails in the Sierra Buttes, Tahoe, Plumas and Lassen National Forests. As part of their fundraising efforts, they produce two exceptional cycling events each year, the Downieville Classic which is one of the Best MTB Events in the Northwest and Lost and Found Gravel Festival which is one of the Best Gravel Cycling Events in California. The Sierra Buttes Trail Stewardship’s events go beyond being mere races; they are immersive weekend-long festivals that attract participants from around the globe and are often highlighted in leading cycling publications. In addition to race entry fees, they raise funds for their non-profit organization through event partnerships, which enable them to continue trail maintenance and construction. Whether you’re a professional athlete or a spectator seeking an enjoyable weekend in the Lost Sierra, the events cater to everyone. Collectively known as the Lost Sierra Triple Crown, these events present athletes with the ultimate test of fitness and skill, fostering a sense of challenge and achievement.
