Bighorn Trail Run

The Bighorn Trail Run is a remote, rugged ultra in the Bighorn National Forest of Wyoming, spanning the Little Bighorn and Tongue River drainages. It features multiple distances: 18, 32, 52, and 100 miles, offering a tough option for varied experience levels.

Runners encounter extreme mountain weather and wildlife, supported by a crew of volunteers. Features include Mile 90 photos and finish celebration in Dayton. Visit the organization's website for the most recent information.
