Endurance Grid lists 7 mountain bike races in California, from September 2026 to October 2027 across 5 cities.
The mountain bike race calendar in California is busiest in October and September, with races most often in Bakersfield.
Mountain bike races take place on singletrack trails and natural terrain — dirt, roots, rocks, and forest roads. Common formats include cross-country (XC) on looped courses, enduro that times only the downhill stages, marathon XC for longer efforts, and fat bike races on snow or soft terrain.
Race day usually starts with a mass or wave start at a trailhead. XC rewards sustained climbing and aerobic fitness, while enduro is about technical descending. Comfort handling a bike on technical trail is what separates a smooth first race from a rough one.
