Ouray 50 Mile Endurance Run

The Ouray 50 Mile Endurance Run, held in Ouray, Colorado, is a challenging mountain ultramarathon featuring approximately 23,582 feet of elevation gain. Known for its technical and demanding trails, the course is set nearly two miles above sea level amidst stunning mountain scenery. This race is designed to be tougher than many 100-mile events, with a "broken-windshield" format and a rugged, no-frills atmosphere.

Participants must complete volunteer service or pay a fee before the race. The event offers cash prizes for top finishers, subject to drug testing, and emphasizes a gritty, old-school endurance experience with a unique finish marked by two orange traffic cones and a genuine western buckle award.
