Bob Marshall Trail Race

Prepare for an extraordinary journey at the Bob Marshall Trail Race, set for July 18, 2026, in the stunning surroundings of Seeley Lake, Montana. This event offers an unforgettable adventure with distances including a 50K, Marathon (26.2M), Half Marathon (13.1M), 10K, and 5K, catering to a range of trail enthusiasts. Starting and finishing at the scenic Seeley Creek Nordic Trails, participants will immerse themselves in a rugged, no-pavement course that winds through beautiful ski trails, challenging singletrack, and forest service roads.

The Bob Marshall Trail Race is renowned for its breathtaking scenery, unfolding just outside the vast Bob Marshall Wilderness, one of the nation's last true wild frontiers. As you navigate the varied terrain, you'll be surrounded by majestic forested mountains and pristine lakes, with the unique opportunity to spot diverse wildlife such as moose, elk, wolves, and even the elusive grizzly bear. The 50K course features approximately 2,060 to 2,600 feet of elevation gain across two loops, while the Marathon covers about 2,200 feet over two 13-mile loops, and the Half Marathon includes roughly 1,100 feet in a single loop. The 10K offers a more accessible challenge with around 430 feet of elevation gain.

Runners can expect well-supported courses, with a full aid station conveniently located at the start/finish area (which is also central to most loops) and a hydration station midway through the main loop. Historical weather for mid-July typically brings comfortable conditions, with highs around 81°F and lows near 51°F, alongside a minimal 3% chance of precipitation. This race promises not just a physical challenge, but a deep connection with the wild beauty of Montana, making it an essential experience for any trail runner seeking a truly spectacular outing.
