The Rut 50K presents a grueling mountain running experience on the stunning Big Sky Resort property. Participants will navigate a diverse range of terrains, including rugged jeep roads, winding forest trails, and scenic alpine ridges, culminating at the breathtaking summit of Lone Peak. Certain sections of the course, particularly the steep climbs on Headwaters Ridge and Lone Peak, demand technical skill and careful attention due to potential exposure and rockfall hazards. While safety personnel will monitor these areas, it is crucial for runners to remain aware of their surroundings.
