Bob Marshall Trail Races

Embark on an unforgettable trail running adventure at the Bob Marshall Trail Races, set for July 18, 2026, in the stunning Seeley Lake, Montana. This exhilarating event offers distances for every trail enthusiast, including a 50K, 26.2M Marathon, 25K, 13.1M Half Marathon, and 10K. Runners will immerse themselves in the raw beauty just outside the breathtaking Bob Marshall Wilderness, a pristine landscape teeming with majestic, forested mountains, a stunning chain of lakes, and abundant wildlife such as moose, elk, wolves, and even the elusive Grizzly bear.

The course, which kicks off at the scenic Seeley Creek Ski Trails, promises a truly off-pavement experience, winding through beautiful ski trails, rugged singletrack, and Forest Service roads. While the terrain is challenging and varied, it offers mesmerizing, jaw-dropping scenery at every turn. Expect elevation gains of approximately 2600 feet for the 50K (two loops), 2200 feet for the Marathon (two loops), 1300 feet for the 25K (one loop), 1100 feet for the Half Marathon (one loop), and 430 feet for the 10K (one loop). Aid stations are strategically placed, with a full aid station at the start/finish (the center of most loops) and hydration stations halfway through the main loops, offering water, snacks, and Hammer Nutrition products. Typical race day conditions in mid-July feature comfortable highs around 81°F and lows near 51°F, with a minimal 3% chance of precipitation.

Runners are encouraged to wear a hydration vest to stay fueled throughout their journey through one of the nation's last wild frontiers. The course is well-marked with flags, cones, and arrows, but paying attention to the markings is key. With vault toilets and free parking available at the Seeley Creek Nordic Trails start/finish area, the Bob Marshall Trail Races provide a comprehensive and unforgettable experience for those seeking an authentic wilderness run.
