4th Annual Rut Mountain Run

The steep vertical flanks to the top of Lone Peak makes The Rut one of the most challenging ultra-marathon courses in the world.

Elite mountain runners from around the world will converge on Big Sky Resort Sept. 2^nd – 4^th to compete in the 4^th Annual Rut Mountain Run, organized by the Runner’s Edge in Missoula and sponsored by Big Sky Resort and Salomon. It’s the only sanctioned race in North America that’s part of the International Skyrunner Federation’s 2016 Skyrunner World Series – which is why it attracts so many of the top athletes from across the globe. Skyrunner is the most prestigious mountain running series in the world.

There are 1,800 total racers registered in at least one of the four primary races: The Lone Peak Vertical Kilometer, 50K, 28K and 11K. There’s also a 1K kid’s race on Saturday. The 50K, which accommodates 625 racers, filled up 15 hours after registration opened.
