John Colter Run

Three Forks, United States • 19 Sep 2026

Event Overview

The John Colter Run is a trail race held at Missouri Headwaters State Park, located near Three Forks, Montana. The event commemorates a historical escape by re-enacting a specific cross-country journey through rugged terrain. The race is limited to 300 participants and does not permit walkers due to time constraints and the specific nature of the course.

Course Details

The course covers approximately 7.5 miles. It begins with 1.5 miles on a paved and gravel country road before transitioning into 5.5 miles of rugged trails. The trail sections are marked with various objects including rock cairns, flags, stakes, and bones. The terrain features two railroad crossings; the first is managed by crossing guards, while the second requires runners to pass under a bridge through water and mud.

Water and mud are significant features of the final section of the race. Participants encounter two major water crossings in the last quarter mile, including a crossing of the Gallatin River where water depths can reach waist-high. A safety rope is provided for the river crossing. One water station is located approximately four miles into the run.
