Prepare for an unforgettable autumn adventure at the Indian Creek Trail Runs, set for Saturday, October 17, 2026, in Sedalia, CO. This "Fall Classic," the oldest official race of the Human Potential Running Series, invites runners to explore the Front Range's exceptional and often-seldom-used singletrack trails. Choose your challenge from distances of 50M, 55K, 15M, or 5M, each promising a spectacular journey through Colorado's changing landscape.

Runners will navigate a hilly course ascending and descending through lower and upper montane ecosystems, ranging from approximately 5,000 to 8,000 feet in elevation. The trails wind through picturesque lodgepole pine forests, vibrant aspen groves, and tall grasses, interspersed with dramatic red rock formations reminiscent of Red Rocks Amphitheater. Expect breathtaking views that offer glimpses of the Denver cityscape and towering 14ers. Typical race day conditions in mid-October feature comfortable highs around 63F and cool lows of 34F, with a minimal 4% chance of precipitation, creating ideal running weather amidst the golden aspens and fiery scrub oak.

The Indian Creek Trail Runs are renowned for their well-organized event structure and personal touch, featuring well-stocked aid stations to support runners throughout their journey. The start and finish line at Indian Creek Campground provides a central hub, though crew access is primarily limited to this area. With a course described by runners as challenging, beautiful, and deeply enjoyable, the Indian Creek Trail Runs offer a unique opportunity to experience some of Colorado's most pristine fall scenery on foot.
