The Scout Mountain Ultras are not your average trail race. Set in the rugged Caribou-Targhee National Forest outside of Pocatello, Idaho, these courses take you deep into wild terrain where the mountains write the rules and the weather keeps you guessing. One year you might be glissading down snowfields, another year you could be battling scorching heat. Either way, you’re in for an unforgettable mountain running experience.

Every distance here delivers big climbs, epic singletrack, and that raw wilderness feel. The legendary 100 mile course will test the toughest runners with more than 22,000 feet of gain. The 50 mile and 50 kilometer options dish out long days on snow, mud, and high ridges. And if you want to get a full taste of what Scout Mountain is all about, the 21 mile loop summits the peak itself with some of the best trails of the whole event. This race is as real as it gets—challenging, beautiful, and absolutely worth every step.
