Wyoming Range 100-Mile Endurance Run
The Wyoming Range 100 is a point to point mountain ultramarathon held August 7-9, 2026 in Bridger-Teton National Forest, running from Middle Piney Lake to Box Y Ranch. The course distance is 105.7 miles with roughly 24,000 feet of elevation gain and a maximum elevation near 11,378 feet.
The route passes through high country terrain and is marked on a course map and downloadable GPX file. Organizers list 11 aid stations including the finish; aid stations are spaced at roughly 10 miles apart. The official cutoff for the race is 48 hours. Recent results show an average finishing time near 41 hours 15 minutes and a finishing rate of about 75.6 percent.
Logistics information is consolidated in an event manual that may change based on post-winter trail conditions. The event operates under a special use permit through the United States Forest Service and partners with Friends of Bridger-Teton for stewardship. The race is designated as a Hardrock qualifier and is not a Western States qualifier. Finishers receive a commemorative finisher buckle.
