Embark on an unforgettable alpine challenge with the Aspen Backcountry race, set for August 1, 2026, in the breathtaking mountain town of Aspen, Colorado. Offering both Marathon and Half Marathon distances, this event plunges runners deep into the stunning Elk Mountains on courses run almost exclusively on dirt trails. You can expect typical race day conditions to be invigorating, with highs around 75°F and lows near 49°F, and only a 9% chance of precipitation, providing ideal weather for a high-country adventure.

The Aspen Backcountry courses are renowned for their diverse terrain, featuring a mix of single-track, double-track, and dirt roads, along with challenging ascents and exhilarating descents. Runners will navigate significant elevation gains, reaching peaks over 10,000 feet, and traverse iconic trails like Smuggler Mountain, Sunnyside, and through pristine aspen groves and alpine meadows, all while enjoying spectacular panoramic views of the Elk Mountains and the town of Aspen below. While remote aid stations provide essential support with water, electrolyte drinks, and fruit, this is a limited-support, cup-free course, encouraging runners to carry their own hydration gear and be prepared for a true backcountry experience.

Beyond the rigorous trails, the Aspen Backcountry race, organized by Aravaipa Running, stands out for its vibrant atmosphere. The event starts and finishes at Rio Grande Park, conveniently located in downtown Aspen. What makes this race truly unique is its exciting coincidence with Aspen's Annual Duck Derby, transforming the finish line into a lively festival complete with live music, food trucks, and family-friendly activities, ensuring a memorable celebration for every finisher. This event, which has a history dating back to 2011, promises not just a race, but a full day of mountain community spirit and unforgettable accomplishments.
