Schedule of Events

6:00 AM - IMTUF100

CUTOFF: 36 hours. Must finish by 6:00 PM MST on Sunday September 22 for an official finish. If we must stagger the start and you start after 6 AM, this will be considered in your finish time.

COURSE: 100 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 include bear, wolves, lions, moose, deer, eagles, goshawks and more.

DIFFICULTY: 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 in difficulty, but more technical.

STATS: 100+ mi, 22,000 gain.

Just expect a long and hard journey and you will enjoy the adventure.
