About Bighorn Mountain Wild and Scenic Trail Runs

Bighorn Trail Runs offer several distances –  18 miles, 32 miles, 52 miles and 100 miles. The courses are  designed to maximize the exposure of the participants, their families, and race volunteers to an extremely scenic, wild, and primitive area of the geologically unique Bighorn Mountains. 

The course allows maximum flexibility to accommodate a variety of unpredictable weather conditions or adverse course contingency courses that would be aesthetically acceptable to the trail runner.

This race is extremely challenging due to the rugged terrain of the Bighorn Mountains, and has become a favourite among avid trail runners. The course, an out-and-back, is at elevations of up to 10,000 feet, among fields of wildflowers and breathtaking scenery. The majority of the course is on rugged mountain trails and 4-wheel drive roads.
