About
Get ready for an epic summer adventure at the Montana wilderness! Starting July 11, 2026, we're kicking off a series of heart-pumping trail races — from the scenic Yellowstone Trail Marathon to the wild Bob Marshall Trail Races. With distances ranging from 5K to 50K, there's a challenge for every runner amidst the stunning landscapes of West Yellowstone, Seeley Lake, and Thompson Park.
As you push your limits, you'll not only earn bragging rights but also some cool swag: a custom race medal, bib, and sticker, plus Hammer Nutrition products to keep you fueled. We're talking certified courses with full aid station support and recorded results to immortalize your achievement. And hey, don't forget to snag a discounted race shirt to remember the days you conquered the great Montana outdoors!
