Wyoming Range 100-Mile Endurance Run
The Wyoming Range 100 is a fully supported 100 mile endurance run organized by Everlong Endurance at Box Y Ranch near Middle Piney Lake, Wyoming. The course follows the Wyoming Range National Recreation Trail and places runners in deep wilderness for extended stretches.
The route includes roughly 24,000 feet of climbing and an average elevation near 8,600 feet. Participants should expect rough trail that may require way finding, long distances between aid stations, and exposure to high mountain weather including snow, lightning, and white-out conditions. The event takes place in grizzly country and requires participants to carry bear spray.
Entry requires a service commitment of at least eight hours of trail work or wildlife habitat restoration completed at least two weeks before race day, or a donation of $80 to Friends of the Bridger Teton with receipt provided. Trail work is validated with a stewardship form.
Required gear includes a Garmin GPS device for live tracking and bear spray; rentals are available for those who need them. The race serves as a Hardrock qualifier. Registration opens on Mon. Feb 1, 2027 at 12:00 AM MT. Event materials such as an event manual and information on drop bags, course conditions, gear requirements, parking, and weather are provided by the organizer.
