Kessel Run Ultra 40 Miler

2026

The Kessel Run Ultra 40 Miler takes place each November in Fruita, Colorado's North Desert, offering runners 40 miles of high desert singletrack with around 4,100 feet of elevation gain. The course starts on fast, flowing trails before working toward the more demanding terrain of the Zippity-Do-Da Trail, where the climbing becomes steeper and more technical. Running at around 5,000 feet elevation, you'll move through classic Colorado high desert landscape with sweeping views of the San Juan Mountains and Colorado National Monument. The route features a mix of smooth singletrack and more challenging sections with sharp ups and downs, particularly as you encounter the Zippity trail system. November typically brings cool, crisp conditions that many runners find ideal for longer efforts, though desert weather can be unpredictable. This race suits runners comfortable with moderate elevation gain spread over substantial distance, and those who don't mind technical sections mixed with runnable terrain. If you prefer consistent, predictable climbing or need frequent crew access, this might not be your best fit—crew is only allowed at the finish line. Runners who enjoy varied desert singletrack and can handle sustained effort over rolling, sometimes technical ground will likely find this course engaging.
