Estes Epic Heavy Half

A 15-mile out-and-back trail run through Arapaho Roosevelt National Forest above Estes Park, sharing the same rugged mountain terrain as the flagship 50K. The course starts at Stanley Park at 7,500 feet and climbs into the backcountry, with two aid stations providing three total stops. An 11-hour race window makes it accessible for trail runners building toward longer distances, while the elevation and mountain terrain still deliver a genuine challenge.
