The Scout Mountain Ultra Trail is a challenging course that goes through the Caribou-Targhee National Forest. Choose from three races: 35 km, 60 km and 100 km, but if you choose the latter, "come prepared for just about anything" because spring in Idaho can be unpredictable. Oh, and then there's the vertical gain. The 100 km course has 13,200' of gain and 13,200' of loss, that's because the race takes place in the "Bannock and Pocatello mountain ranges surrounding Pocatello, Idaho." The organizers want you to know what you're getting into, but if you're up for the challenge, the finish line comes with your personal satisfaction along with prizes handmade by local artists and dinner cooked by local chefs.
