Wyoming Range 100-Mile Endurance Run
The Wyoming Range 100 is a point-to-point trail endurance event in Bridger-Teton National Forest, running from Middle Piney Lake to Box Y Ranch. The course covers 105.7 miles with about 24,000 feet of elevation gain and reaches a maximum elevation of 11,378 feet at Wyoming Peak. The event is scheduled for August 7-9, 2026 and uses a 48 hour cutoff for finishers.
Logistics for participants are detailed in an event manual intended for runners, pacers, crew, and volunteers; the manual may be updated based on post-winter trail conditions. The field is limited to 100 runners; a waitlist is maintained and there is no fee to join the waitlist until an invitation is accepted. Organizers will provide Garmin tracking devices for all participants this year; previously rented devices through third parties will be refunded after registration is processed.
Support on course includes aid stations spaced at roughly 10 mile intervals. The race operates under a special use permit with the United States Forest Service and lists Friends of Bridger-Teton as a stewardship partner. Course information such as maps, elevation profile, arrival time estimates for aid stations, and results are provided by the organizers for pre-race planning and post-race review.
