Wyoming Range 100-Mile Endurance Run
The Wyoming Range 100 is a supported trail endurance run held in early August 2026 in the Wyoming Range, from Middle Piney Lake to Box Y Ranch in the Bridger-Teton National Forest. The course is a point to point route covering 108 miles with approximately 24,000 feet of elevation gain and an average elevation near 8,500 feet. The highest point on course is Wyoming Peak at 11,378 feet.
Aid stations are spaced roughly ten miles apart. The race operates with a 48 hour cutoff. Large sections follow the Wyoming Range National Recreation Trail and include rough, intermittently marked or disappearing trail. Runners may encounter high-elevation weather and terrain such as snow, lightning, or white-out conditions, and the route passes through grizzly country.
The event is listed as a Hardock 100 qualifier. Organizers provide a course map, an aerial flyover, and an event manual that details logistics, mandatory gear, and aid station arrival estimates. Stewardship partners include Friends of the Bridger-Teton and City Kids Wilderness Project. The race requires preparation for long, remote stretches and variable mountain conditions.
