Harriman Trail Run

The Harriman Trail Races deliver a trail running experience that feels handcrafted for adventure seekers. Set in the wild beauty of Island Park, Idaho, this event combines the serenity of quiet forests and sweeping meadows with the thrill of challenging, scenic singletrack. Wildlife sightings, panoramic views of the Teton Mountains, and the flowing Henry’s Fork River make this an unforgettable race environment.

Now in its ninth year, Harriman has earned a reputation for its thoughtfully curated vibe, gourmet-style aid station, and the camaraderie of a tight-knit trail running community. Whether you are chasing a new distance, doubling back for the 50K, or taking on the speedy 8.1 miles, the Harriman Trail Run promises trails that are as joyful as they are rewarding. After the finish, join fellow runners along the river for food, drinks, and celebration.
