Ouray Mountain Trail Run

Ouray Mountain Trail Run takes place in Ouray, Colorado, on September 19, 2026. The event offers a single trail format, a 13-mile race. Ouray sits in the San Juan Mountains of southwestern Colorado at roughly 7,800 feet, so the distance should be read as a mountain half marathon rather than a standard 13 miles.

This is a race for runners who enjoy climbing and want a high-altitude challenge over a distance that still fits in a morning. It suits trail runners with at least one half marathon behind them and the patience to power-hike when the trail steepens. Arrive a couple of days early if you can, to take the edge off the altitude, and start at a controlled effort. In your 12-week build, include weekly hill repeats, long runs with sustained climbs, and a few descents on rocky trails to prepare your quads. If poles are permitted, they can be a real help on the steep sections.
