COURSE: 102.9 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 include bear, wolves, lions, moose, deer, eagles 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, but more technical. Fast times are hard to come by...our course records are 19:52 by David Ayala and 26:42 by Darla Askew.
STATS: Various GPS tracks from racers have measured 100-105 miles. My best measurement is 102.9 miles using Garmin tracks and Topofusion mapping software. Do not trust your on-course GPS measurements out here. They are frequently far off. On any 10 mile run I go on in this area, my Garmin may show +/- 1 mile.
Just expect a long and hard journey and you will enjoy the adventure.
Pre-Race Briefing (highly recommended for 100 milers): 6:00 PM on Friday, September 15, 2017. The briefing will be at Burgdorf Hot Springs near the starting line. We will go over safety issues, the course, rules and do some Q&A. 30K runners are encouraged to attend if you have any questions about your race.
