Wyoming Range 100-Mile Endurance Run
Held August 7-9, 2026, the Wyoming Range 100 is a point to point mountain trail event that runs from Middle Piney Lake to Box Y Ranch inside Bridger-Teton National Forest. The course is routed through high country and is documented with a course map and a downloadable GPX file.
The official distance is 105.7 miles with about 24,000 feet of elevation gain. There are 11 aid stations spaced at roughly 10 miles apart. The race uses a 48 hour cutoff. The published average finishing time is 41:15:30 and the historical finishing rate is 75.6 percent. The event is a Hardrock qualifier.
Organizers provide an event manual that serves as a single source of race information; the manual may change as trail conditions evolve after winter. Online course planning resources include a CalTopo view and a GPX download. Aid stations are color coded for crew access: green stations allow crew access, yellow stations are crew only with no volunteers, and red stations are closed to crew.
The event lists Friends of Bridger-Teton as a stewardship partner and operates under a special use permit through the United States Forest Service. Visit the organization's website for the most recent information.
