The Colorado 24 Hour Run, set for October 31, 2026, in Fort Collins, CO, offers an exceptional opportunity to test your limits across 6-hour, 12-hour, and 24-hour distances. Held at the scenic Colorado Youth Outdoors – Swift Ponds Campus, this race challenges runners on a USATF-certified, 1-mile flat dirt loop that encircles a tranquil nature pond. The course is celebrated for being easy on the feet and offers picturesque views, often frequented by local fauna like raptors, cranes, and various waterfowl. With only a two-foot elevation variation, it’s designed for runners to find their rhythm and push for personal bests in a supportive, welcoming environment.

Runners can anticipate comprehensive support throughout the event. A fully stocked aid station at the start/finish pavilion offers a rotating menu of hot and cold options, including vegetarian, vegan, and gluten-free choices, along with Gnarly Nutrition sports drinks and Naak gels. For those tackling the longer distances, directions on the loop change every six hours to provide variety. Typical race day conditions in late October include highs around 60°F and lows around 31°F, with a low 4% chance of precipitation, creating ideal cool-weather running.

Beyond the course, the Colorado 24 Hour Run fosters a strong community atmosphere. Crews can set up personal aid tents adjacent to the main aid station, and runners have access to an indoor lodge at Richardson Hall for respite. Whether you're aiming for a new furthest distance, your fastest marathon, or even a 100-mile belt buckle in the 24-hour event, this Trail Sisters Approved race promises a memorable experience and a top-notch post-race celebration to cap off your achievement.
