The Mammoth Tuff Gravel 2026 cycling event is a prominent gravel racing and cycling adventure held annually in Mammoth Lakes, California. Founded by professional cyclists Amanda Nauman and Dave Sheek, the event debuted in 2021, quickly establishing itself as a must-attend for gravel enthusiasts. The vision for Mammoth Tuff Gravel 2026 emerged from Nauman and Sheek’s passion for gravel riding and their desire to showcase the Eastern Sierra region. Mammoth Tuff Gravel 2026 has become an iconic event in the gravel cycling scene by blending challenging routes, high-altitude riding, and a welcoming community atmosphere.

The Eastern Sierra offers a unique combination of high-altitude landscapes, rugged terrain, and scenic beauty that few other events can match. Riders traverse dirt roads and trails that showcase towering peaks, alpine meadows, and ancient geological formations. The event caters to riders of all levels by offering multiple route options, including shorter, more accessible distances and long, grueling courses for elite and endurance riders.

Mammoth Tuff Gravel’s association with the UCI Gravel World Series further elevates its profile. As a qualifying event, it draws top talent from around the globe, allowing riders to compete for a chance to participate in the UCI Gravel World Championships. Strambecco rates Mammoth Tuff as a Best-in-Class gravel event spanning California and the greater Southwest.

There are three course options: TUFF is shortest option estimated at about 40 miles (63km). TUFFER is the medium option at 60-75 miles (96-120km). And the long course is TUFFEST at 85-100 miles (137-160km). TUFF or 40-mile route is not a qualifying distance for the UCI Gravel World Championships. The TUFFER course serves as a qualifier for men over 60 and women over 50, while the TUFFEST course is the official qualifier distance for all younger categories. Each route has a neutral roll from town to the first gravel segment and the full course includes a percentage of paved. There are aid stations and support available along your selected ride.

Mammoth Tuff is more than just a race; it celebrates gravel cycling culture. The event’s organizers prioritize creating a supportive and festive environment with pre-ride socials, post-ride celebrations, and opportunities to connect with fellow riders. At an elevation of over 7,800 feet, the area provides a high-altitude training ground for cyclists.
