About the Headwaters Bank Run (26th Annual)
The course runs on the Headwaters Trail System, mostly flat, passing the Three Forks Ponds and crossing the Madison River on a pedestrian bridge. The half marathon extends into Headwaters State Park, where the Jefferson, Madison, and Gallatin rivers meet. Each distance is color-coded on the trail, so navigation is straightforward once you know your markers.
The races start at Veteran Park in downtown Three Forks, near the Sacajawea Hotel and the Train Depot Museum. Snacks and beverages are out after the race, and water is available along the course. Timing is handled by chip, so results come through cleanly.
