The Mammoth Tuff Gravel 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 event's spirit is inclusive, focusing on camaraderie and fostering a community of gravel enthusiasts.
Mammoth Tuff’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. This affiliation underscores the event’s prestige and competitive edge. Strambecco rates Mammoth Tuff as a Best-in-Class gravel event spanning California and the greater Southwest.
Course Description
The 2025 courses for Mammoth Tuff will be finalized and released a few weeks before the event. Below are the details from 2024:
There are three distances: 40, 70, and 90 miles. The 40-mile route is not a qualifying distance for the UCI Gravel World Championships. The 70-mile course serves as a qualifier for men over 60 and women over 50, while the 90-mile course is the official qualifier distance for all younger categories.
In the 90-mile course, riders begin with a 5-mile paved section before transitioning to the first gravel segment from miles 5 to 16. This is followed by another paved stretch from miles 16 to 31, taking riders east to the lowest point of the course. The return to the finish involves a mix of gravel and asphalt. The course consists of 63% gravel and 37% paved roads.
The shorter 70-mile course bypasses the eastern section of the 90-mile route but features different tracks at the beginning, providing its own unique challenges and scenery.
