The Scout Mountain Ultra events take competitors on a challenging tour of the Caribou-Targhee National Forest outside of Pocatello, Idaho. This is a rugged, mountain-running event in the spring, in Idaho. Be prepared for tough course conditions and unpredictable weather. Approach this course and the area with respect and come prepared for anything from hail and snow to blazing heat.

All three distances are solo – no relays or teams.

For the truly hardcore runner, the full 100-mile course is for you. This major test of endurance comprises three “legs” as runners navigate a challenging ~23,800 ft of vertical gain (and loss).

For the slightly less masochistic runner the 50 mile course (actually 53.8 miles) traverses legs 2 and 3 of the 100-mile route. With over 10,900′ of vertical gain (and loss) and the potential for very snowy and muddy conditions, this route takes runners through an incredible challenge.

Our favorite section of the course is leg 3, which is exactly why it’s the core of the 21 mile route. A glorious loop that summits Scout Mountain. With over 5,400′ of gain (and loss) and the best single track of the whole event, this is one incredible loop. This leg will most certainly have some snow. With a strong winter, this leg could be heavily snow-covered.
