Run Rabbit Run 50 Mile

2026

The Run Rabbit Run 50 takes place in September in Steamboat Springs, Colorado, following an out-and-back course from the ski area base to Rabbit Ears Mountain. With 11 aid stations spread across the 50-mile route, runners face a challenging mountain course at altitude with a 15-hour cutoff. The course climbs from the Steamboat Springs base area through varied terrain toward Rabbit Ears Mountain before retracing the route back. Expect significant elevation gain and the typical challenges of Colorado mountain running—altitude, weather variability, and exposed sections. The single turnaround at Rabbit Ears means you'll see the course twice, which can be mentally helpful or challenging depending on your perspective. Dumont aid station serves as the only crew access point, so logistics require some planning. This race suits experienced mountain runners comfortable with sustained climbing, altitude, and potentially changing weather conditions. The September timing in Colorado means anything from warm sun to snow is possible. Runners who prefer point-to-point courses or those new to high-altitude racing might find the out-and-back format and elevation more demanding than expected.
