Grinduro California

California · USA · organised by Sierra Buttes Trail Stewardship
When
Mid-September, annually; 2027 date not yet published
Distances
82 · 37 km
Climbing
2,195 m

Gravel-and-dirt event based at the fairgrounds in Quincy in the northern Sierra. Only four short timed segments count toward results, so most of the 51-mile loop is ridden at your own pace. The shorter Grindurito has two segments.

The organiser hasn’t published the next date yet, so we’re showing when it normally runs rather than guessing. The official site will have it first.

Checked against the organiser’s official site on 29 September 2026. Dates, routes and entry conditions change — confirm on the official site before booking flights or accommodation. We are not the organiser and take no entries.
