About

The Rut Mountain Runs take place in the rugged setting of Big Sky, Montana, starting September 10, 2027, and are built for athletes seeking both challenge and adventure. The races include a 50K (30.3 miles / 48.8 km), a 28K (17.8 miles / 28.6 km), a 21K (13.3 miles / 21.4 km), an 11K (6.4 miles / 10.3 km), the Lone Peak Vertical Kilometer (2.5 miles / 4 km), the Trifecta combining the 50K, 28K and VK (52.2 miles / 84 km in total), and the Kids 1K Runt Run.

The routes run around, on and over the iconic Lone Peak. Every participant receives a unique medal, chip timing with live results and a Rut Gear Bag. Elite athletes compete for custom awards for the top five men, women and non-binary athletes, with age-group prizes as well. The course is fully supported by well-stocked aid stations, with full medical and safety coverage from Big Sky Ski Patrol and expert partners.
