Bidwell BUMP 50th Anniversary Oldest MTB Race in the WORLD

About the Event

Established since 1976, this annual technical mountain bike race has grown into an essential fixture for both seasoned riders and newcomers alike. Spanning two days on October 3rd and 4th, 2026, it promises a thrilling experience with diverse courses that cater to all skill levels.
On Saturday, the event kicks off with a beginner cross-country (XC) course designed to introduce new participants to the sport. For those seeking more exhilaration, an electric bike class awaits, offering a unique blend of speed and endurance. Intermediate riders will have their own dedicated path, while seasoned athletes can challenge themselves on the standard XC course.
The highlight is undoubtedly the Super D Downhill (SD) race, where competitors navigate steep descents with technical obstacles. The ultimate test comes in the form of the ALL Mountain event—a combination of XC and SD courses requiring participants to first complete the XC before tackling the downhill section. Note that all SD riders must arrange for transportation from the top start point.
This year’s event has once again sold out, underscoring its popularity among enthusiasts. Early registration is highly recommended to secure a spot. Entry fees remain affordable, making it accessible while still supporting Chico Velo Trail Works through your participation and donations at https://www.pinwheel.us/donate/Donate-To-Trailworks.
Join us for an unforgettable weekend of competition and camaraderie in the scenic setting that has made this race a favorite among mountain bikers. Whether you're competing or spectating, be prepared to witness extraordinary skill and determination as riders push their limits across varied terrain.
