The Sturdy Dirty Enduro 2026 annual event is a highly anticipated women’s only enduro mountain biking race held in the rugged and scenic trails of Raging River State Forest, Washington. Organized by Sturdy B Racing, this event celebrates over a decade of exhilarating downhill and trail racing and is the world’s largest women-specific enduro mountain bike race, dedicated to breaking barriers & creating access in mountain biking.

Known for its unique combination of timed downhill sections and uphill transitions, the Sturdy Dirty 2026 offers a challenging and fun-filled experience for mountain biking enthusiasts of all skill levels. Due to its insane popularity, the event sells out within minutes. Strambecco rates Sturdy Dirty 2026 as one of the Best Mountain Biking Race Events in the Northwest, the Best Cycling Race Events in Washington, and one of the Best Women Only Race Events across sports categories.

Each year, the Sturdy Dirty promises an exhilarating female-only enduro experience amidst rugged trails. This celebratory race offers multiple route options, each designed to challenge riders of varying skill levels while showcasing the diverse terrain of the region. Participants should possess at least intermediate mountain biking skills and fitness levels to comfortably navigate the course.

On course, participants will ride mostly single-track with some gravel roads between stages, with all racing occurring on single-track. Racers should expect lines at each stage and may want to bring a coat for comfort while waiting. Racers will be sent off in 30-second increments to maintain reasonable lines, with timers adjusting intervals as needed.

The Expert/Pro Route presents four stages that test the mettle of highly skilled riders with technical descents and demanding double black diamond trails, including sections on Plum Creek DH, CCDH 3, 4, 5, and 6, Upper PT, and Lower Pop-n-Tops & Flow State.

Intermediate riders will find the Sport Route engaging, featuring a mix of technical challenges and flowy sections on A3, Plum Creek DH, A1, and Lower Pop-n-Tops & Flow State.

For those new to racing, the Beginner Route offers manageable trails with a few technical features on A1, A3, and Lower Pop-n-Tops & Flow State, providing an ideal introduction to mountain bike racing.

Additionally, the Lite and Adaptive Routes cater to riders with adaptive needs or those seeking a less intense experience, ensuring inclusivity within the event.

The Lite, Beginner, and Sport race segments will primarily feature blue downhill trails, which are generally winding and include roots, rocks, and rollable jumps and drops. Riders should aim to stay on their bikes for most of the trail, though walking a few challenging features is acceptable.

Throughout the race, strategically located aid stations provide essential supplies like water, nutrition, and first aid. While riders are encouraged to be self-sufficient, mechanical support is available at key points on the course to assist with bike repairs.

Participants can expect a vibrant post-race atmosphere, with awards given to top finishers in each category and a raffle offering exciting prizes. A post-race party featuring food, drinks, and entertainment celebrates the 10th anniversary of the event.

The organization uses an inclusive definition of “woman” and “female.” They welcome anyone who experiences life as a woman, identifies as a woman, or is gender fluid, gender diverse, queer, expansive, questioning, or non-binary. All are invited to spectate and volunteer, but only women are permitted to race.
