Headwaters Relay

Embark on an extraordinary three-day adventure with the Headwaters Relay, a challenging and immensely rewarding team-supported race spanning 232-235 miles through the rugged and breathtaking backcountry of Southwest Montana. Starting at Headwaters State Park near Three Forks, the course is predominantly (95-98%) on dirt and two-track roads, guiding teams through a spectacular tapestry of landscapes including the Tobacco Root Mountains, the rural Jefferson and Ruby Valleys, and the majestic Gravelly Range, where elevations can reach nearly 10,000 feet. Prepare for serious climbs and descents, with stunning views of areas like Axolotl Lakes and the towering Sphinx Mountain across the Madison Range. This limited-field event, scheduled for July 31st, 2026, offers a unique opportunity to trace the historical path to the true headwaters of the Missouri River, culminating at the ice-cold Hellroaring Creek in the Centennial Valley, where a ceremonial dip awaits.

What sets the Headwaters Relay apart is its distinct format: unlike many continuous relays, teams do not run through the night. Instead, each day has a definitive start and end point, allowing for team camping and shared experiences under the Montana sky. Individual legs, ranging from 1 to 6 miles, vary in difficulty and terrain, promising a diverse running experience for every team member. This race emphasizes self-sufficiency; there are no traditional aid stations or course marshals. Teams are responsible for their own support, including food, liquids, and navigation using detailed written leg descriptions to find unmarked exchange points. Typical race day conditions in late July feature comfortable lows around 50°F and highs around 88°F, with a minimal 4% chance of precipitation, though runners should be prepared for varying mountain weather.

The Headwaters Relay has earned a reputation for fostering incredible camaraderie and a "cult-like following" among its participants, many of whom return year after year for this unparalleled challenge. Runners consistently describe it as a grueling yet incredibly rewarding "life-highlight," celebrating not just the physical feat but the deep bonds formed over three days of shared effort and adventure. Soaking tired legs in the Beaverhead and Madison Rivers at the end of the first two days are cherished experiences, adding to the unique charm of this epic Montana journey.
