About the Bob Marshall Trail Races
The course runs out of a Nordic ski trail center on the edge of the Bob Marshall Wilderness, mixing groomed ski trails with rugged singletrack and forest service roads. There is real elevation gain, especially on the longer options, and no pavement anywhere. Moose and elk are a genuine possibility, not just a marketing line.
Packet pickup and a pre-race meeting both happen at the trailhead start area on race morning, so there is no separate trip the night before. The finish line has snacks and refreshments waiting.

The Bob Marshall Trail Races has been held every year since at least 2021. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 25, 2026.
