30K
The 30K offers a substantial challenge without the ultra-distance commitment of the 50K, making it an ideal stepping stone for runners looking to test their limits on McCall's demanding terrain. This distance provides enough time on the trails to experience the full character of the course while maintaining a pace that allows runners to appreciate the technical sections and elevation changes. Perfect for experienced trail runners seeking a hard effort that finishes strong, or those building toward longer ultra distances who want to practice race-day strategies without the extended time commitment.
50K
The 30K follows the classic "Legend of Bear Pete" loop, gaining approximately 3,500 feet of elevation on technical alpine singletrack through the Payette National Forest. The 50K extends the challenge by beginning with the Willow and Jeanette Creek Trails, including a climb of Crystal Mountain before joining the Bear Pete loop to the finish. Both courses showcase the demanding terrain that made the original IMTUF100 legendary among mountain ultrarunners. Runners navigate narrow singletrack, steep climbs, and technical descents while surrounded by the pristine wilderness of central Idaho's high country.
