Endure Trail Runs

Endure Trail Runs, hosted by the Human Potential Running Series, is an annual event held at Mueller State Park in Divide, Colorado. The 6th edition features multiple race options including a unique 12-Hour timed event where runners draw colored balls to determine their next loop, a marathon, half marathon, and 10k—all on scenic single and double-track trails with no pavement. The event offers a supportive, no-pressure atmosphere with a generous 11-hour cutoff for the timed races.

The start/finish and aid station are located at the Pisgah Camping Area, providing well-stocked support. Camping is available on-site with limited space, and the event emphasizes inclusion, community, and respect for the natural environment.
