Mountains to Meadows Endurofest
10 years later, Grinduro returns to Quincy, back where it all started, to celebrate our birthday with the perfect party-to-race ratio at the ultimate California gravel race, only to be bolstered with the high-speed, magically flowy Mt. Hough Enduro MTB/eDuro.
What it is: A weekend of racing and partying in the Lost Sierra where riders may choose to race Grinduro Saturday, the Mt. Hough Enduro MTB/e-MTB Enduro Sunday, or both for serious bragging rights. In short, Grinduro is just what the name suggests: Gravel Road Race + Mountain Bike-Style Enduro = one long loop of pavement and dirt, where finishing times aren’t based on overall loop time but four timed segments.
The Dirt: Mt. Hough has developed as a singletrack destination over the last ten years, now boasting more than 70 miles of mostly flowy singletrack. Forest service roads criss cross the mountainside like a grid to nowhere, and everywhere, making the mountain an ideal playground for gravel enthusiasts. Mountains to Meadows Endurofest makes the best of these two dirt worlds, coexisting in one magical weekend of racing. Not a racer? Not to worry. Come for the vibes, the music, and to volunteer!
Details: 1.5 hours from Lake Tahoe & Reno. 3 hours from Sacramento.
Come spend a beautiful fall weekend with us in the Lost Sierra and support the work of Sierra Buttes Trail Stewardship—all ticket proceeds benefit SBTS’ work to revitalize mountain communities, using trails as the tool.

Mt. Hough Enduro and e-MTB Enduro Race Information
Sunday, September 14th, 2025
The MTB and e-MTB Enduro is a BLIND ENDURO FORMAT. Racers will not know the timed stages until they roll up to ‘em, keeping the race filled with stoke and anticipation. The race is one long loop of dirt, where finishing times aren’t based on overall loop time, but timed DH segments. Racers only need to make the cutoffs for each stage.
Mt. Hough is known for its high speed, flowy dirt goodness. Not your typical super gnar enduro, most of the trails and timed stages are fast, flowy intermediate (blue square) type trails. Be ready for SPEED!
