Colorado 24 Hour Run

Hosted in Fort Collins, Colorado, the Colorado 24 Hour Run offers 24-hour, 12-hour, and 6-hour events, including relays, on a single 1-mile dirt loop. The course is described as Colorado’s most scenic flat dirt loop—fully supported and easy on feet and eyes. Runners can tackle distances individually or in relay teams, choosing to race day and night while chasing personal bests, whether it’s the farthest distance, a marathon, or a 50K.

The atmosphere is welcoming and community-focused, with a strong post-race experience designed to nourish participants and keep the stories flowing. The race is held at 4927 E. County Road 36 in Fort Collins. Visit the organization's website for the most recent information.
