Lace up for an unforgettable alpine adventure at the Deep Creek Trail Half Marathon, set to challenge and inspire runners on September 26, 2026, in the breathtaking mountain town of Telluride, Colorado. This 13.1-mile high-elevation, high-altitude race promises spectacular views and incredible landscapes as you traverse the San Juan Mountains during the peak of fall foliage.

The challenging course, with approximately 3100 feet of total elevation gain, is predominantly single-track, covering about 95% unpaved trails. Starting near the Telluride Airport on Last Dollar Road, runners will journey toward Deep Creek Corral before ascending into magnificent aspen-filled woods along the Deep Creek Trail. The route then winds its way back to the heart of Telluride, culminating at Oak Street Park, nestled between the historic Sheridan Opera House and the County Courthouse. Aid stations along the course are well-stocked with water, Tailwind, fruits, and a variety of sweet and salty snacks to keep you fueled, with the second aid station offering a more diverse selection.

Despite its demanding terrain, the Deep Creek Trail Half Marathon is known for its supportive atmosphere and five-hour time limit, making it accessible for a wide range of fitness levels, including walkers. Typical race day conditions in late September offer cool, refreshing temperatures, with highs around 67°F and lows around 41°F, and only a 9% chance of precipitation, creating ideal running weather amidst the vibrant autumn scenery. Prepare for a truly unique and engaging trail running experience in one of Colorado's most stunning destinations.
