Set for Saturday, September 6, 2025 in Salmon, Idaho, the Salmon Marathon & Half Marathon welcomes runners to a unique high-country road challenge nestled within the rugged Lemhi Valley. Known for its dirt-road character and scenic mountain setting, the half marathon shares much of the herculean marathon route: roughly 16 miles of dirt and gravel, transitioning to paved road for the final stretch into town.
The course features two brief but notable climbs—just after mile 7 and again past 13.1—before gently descending toward the finish. While mostly net downhill, the mix of terrain keeps fatigue and pace management real . Aid stations are stocked with water, electrolytes, and gels and include port-o-lets—an appreciated touch in rural Idaho.
Runners praise the volunteer support and rustic backdrop:
“Both the full and half… friendly volunteers at the aid stations, with beautiful scenery in the backdrop.”
Expect wraparound views of the Salmon River, surrounding mountains, and wildflower-lined dirt roads. While the surface roughness may deter those chasing PRs, this half is a standout for trail-to-road and adventure-seekers looking for something different in the 13.1-mile distance.
