Endure Trail Runs

Divide, United States • 16 May 2026

Endure Trail Runs takes place at Mueller State Park in Divide, Colorado, with four events: a 12‑Hour endurance race and standard distances of 10K, Half Marathon, and Marathon. The 12‑Hour race uses a unique “tiny balls” mechanic: runners draw colored balls to determine which loop to run next, tallying miles accumulated in up to 12 hours. The shorter distances also feature generous 11‑hour cutoffs. Courses are all on double-track and single-track trails with no pavement, anchored by a single, well-stocked aid station at the Pisgah Camping Area. On-site camping is offered; the event emphasizes community, inclusion, and a supportive atmosphere. Visit the organization's website for the most recent information.
