Scout Mountain Ultras

The Scout Mountain Ultras are a series of demanding mountain races near Pocatello, Idaho: the 100-mile (160.9 km) starts on June 4, 2027, at 10 a.m., followed on June 5 by the 50-mile (80.5 km) at midnight, the 50K (31 miles) at 6 a.m. and the 24-mile (38.6 km) race at 8 a.m. Every course crosses the summit of Scout Mountain in the rugged Caribou-Targhee National Forest, with breathtaking scenery and significant elevation gain.

Recognized as the top ultramarathons in southeast Idaho since their creation, these races are designed for athletes who enjoy technical terrain and responsible environmental stewardship, and competitors are encouraged to learn about sustainable racing. Detailed information on courses, logistics and support is available online. Given the intense difficulty of the courses, athletes considering the 100-miler are strongly advised to have already completed a 50-mile mountain ultramarathon.
