John Colter Run

Three Forks, United States • 20 Sep 2025

The John Colter Run is a rugged 7.5-mile trail race held at Missouri Headwaters State Park near Three Forks, Montana. The course starts with 1.5 miles on paved/gravel roads, followed by 5.5 miles of challenging trails reminiscent of the historic Lewis and Clark expedition era. Unique features include two railroad crossings—one with a rare train hold for safe passage—and two water crossings through mud and the Gallatin River, requiring runners to be prepared for waist-deep water. Limited to 300 participants, the race celebrates the legendary escape of John Colter from Blackfoot Indians. Post-race festivities include a barbecue, beer, live music, and awards for top finishers and special recognitions. Visit the organization's website for the most recent information.
