IMTUF 2025 – McCall

The Idaho Mountain Trail Ultra Festival – IMTUF Race 2025 is part of the best trail running series in the US. The 14th running of the IMTUF race starts and ends at Jug Mountain Ranch in McCall, ID, wrapping around for 100+ miles through very steep climbs and descents with TUF footing. On the course you’ll see beautiful summits and ridges, deep canyons filled with pristine rivers and lots of wildlife. The peak elk rut is usually during this time, so bugling bulls are frequently heard and seen. Other wildlife include bear, wolves, lions, moose, deer, eagles and more.
