They are a steadfast group of folks and will be there on the inbound miles welcoming you on your final footsteps towards the finish. Thank the Burlington Northern volunteers and their crew for packing in supplies by foot for your mountain trek. The Trailhead is the gateway to the noble Bighorn Mountains and first remote aid station, Lower Sheep Creek (5025 ft, mile 3.5 outbound, mile 92.5 inbound). Limited aid is provided here by Tongue River Valley Community Center on the outbound trip. Runners begin their outbound journey with views of steep cliffs rising overhead, refreshing glimpses of the Tongue River, and spectacular views of the iconic limestone formation, locally known as ‘The Needle”, as they make their way on a gravel road to the Tongue River Canyon Trailhead (trail #25, 4240 Ft, mile 1.25 outbound, mile 94.8 inbound). The Bighorn 100 begins where the scenic Tongue River has carved out an impressive canyon located approximately 1.25 miles from the Tongue River Canyon Trailhead and 3.5 miles from the Town of Dayton on Tongue Canyon Road (4275 ft).

The Bighorn 100 is one of the classics, demanding you to reach deep down to your core of mental and physical fortitude. Mother Nature provides over 20,500 feet of ascent and 20,750 feet of descent testing the most seasoned ultra-runners with 76 miles of technical single-track trail, 16 miles of rugged 2-track jeep trail road, and 8 miles of gravel road. Participants have 34 hours to navigate this remote, technical out-and-back course (average 2.94 mph). The Bighorn Mountain Trail 100 is an epic mountain endurance adventure crossing through Little Bighorn and Tongue River areas of the Bighorn National Forest. ***īighorn Mountain Trail 100 Run Course Description This event is 'wild and scenic' and mother nature is a contender, but this is a non-negotiable matter before, during, or after the event. Our race director stands behind the aid station captains who have been informed that, under no circumstances will changes be made to the course or cut off times once the race is in progress. However, cutoff times are strictly enforced and are firm regardless of changing course conditions once the race has begun. We understand races sometimes don’t go as planned and this can be frustrating for participants. If any such course changes are required, runners will be fully briefed at the Thursday evening pre-race briefing. ***The race committee reserves the right to respond to potential safety contingencies posed by potentially adverse weather conditions or other course conditions to make 'last minute' course changes.
