Dirty 30

Dirty 30 Mountain Bike Race 

August 23, 2026 • Valley of the Moon (Santa Rosa), CA

The Dirty 30 XL Fondo is a mixed-terrain MTB and drop-bar challenge built around a spectator-friendly figure-8 course on the scenic north shore of Lake Hodges. Riders can choose a single 30-mile lap or step up to two laps for the 60-mile option, with a central staging area that makes refueling and regrouping easy between loops. Expect a blend of gravel, fire roads, punchy climbs, and technical singletrack—designed for riders who want a tough, fun day with strong community energy.
