Prepare for an unparalleled mountain ultra experience at Run Rabbit Run, set to challenge runners on September 19, 2026, in the breathtaking landscapes of Steamboat Springs, Colorado. This iconic race, renowned for its stunning fall foliage and formidable terrain, offers both a 50-mile and two 100-mile options, catering to a wide range of ultrarunning ambitions. Starting at the base of the Steamboat Springs ski area at approximately 6,900 feet, runners immediately begin a demanding ascent, with the 50-mile course tackling nearly 9,000 feet of climbing, traversing Mount Werner (10,568 ft) and the Continental Divide en route to Rabbit Ears Mountain (10,500 ft) before a scenic return. The epic 100-mile journey elevates the challenge further, accumulating around 21,000 to 22,000 feet of vertical gain as it also encompasses Buffalo Pass (10,300 ft) and Emerald Mountain, providing a true test of endurance and spirit through the picturesque Routt National Forest.

Run Rabbit Run distinguishes itself with its unique "Hares" and "Tortoises" divisions for the 100-miler, allowing elites (Hares) to vie for one of the largest prize purses in ultra-running, while Tortoises enjoy an earlier start. Participants consistently praise the race for its spectacular, albeit difficult, high-altitude course, which primarily features runnable singletrack trails, intermingled with some fire roads and sections through town. Aid stations are frequently lauded by runners for being exceptionally well-stocked with a variety of nutrition, hydration, and hot food options at night, all supported by enthusiastic volunteers. Typical race day conditions in mid-September often feature crisp mountain air, with highs around 75°F and lows around 40°F, and only an 8% chance of precipitation, creating ideal conditions for experiencing the vibrant autumn colors that envelop the course.

Beyond the challenging climbs and stunning vistas, Run Rabbit Run is celebrated for its excellent production and a supportive community atmosphere, attracting runners from across the globe. It also serves as a qualifying race for prestigious events like Western States and Hardrock. From the initial climb up the ski hill to the triumphant finish back at its base, this race promises an unforgettable adventure through Colorado's awe-inspiring wilderness, pushing limits and rewarding every "rabbit" with unparalleled scenery and a profound sense of accomplishment.
