IMTUF 100 Mile & Jughandle 20 Mile

Sep 19, 2026 at 6:00 AM

13834 Farm to Market Rd, McCall ID, , USA

100 Mile

103.9 mile loop course in the Salmon River Mountains near McCall, ID. Expect some very steep climbs and descents with TUF footing, beautiful summits and ridges, deep canyons with pristine rivers, and lots of wildlife. The peak elk rut is usually on during this weekend, so bugling bulls are frequently heard and seen. Other wildlife includes bears, wolves, lions, moose, deer, eagles, and more. Very difficult. IMTUF is a Hardrock100 Qualifier for a good reason. It is a little over 100 miles. There is lots of steep climbing totaling over 20,000′ feet of ascent. The footing is rough overall and downright brutal at times. Finishers have often compared it to Wasatch 100, but more technical. Fast times are hard to come by…our course records are 19:22 by David Ayala and 26:42 by Darla Askew.

20 Mile

20 miles with about 5,000′ vertical gain. 5,000′ vertical loss. Loop course with a short (0.5mi) out and back to the aid station at Boulder Lake Trailhead. The course is different than the McCall Trailrunning Classic 20 miler. It goes up and over Jughandle Mountain and down the talus slope to Louie Lake (same first 12 miles as the 100 miler). Then leave the 100mi course on a shortcut from Louie Lake and half mile out and back to Boulder Lake Aid Station. Then the same final 7+ miles as the 100 miler back through Idaho State Lands and finish at Jug Mountain Ranch.
