Yellowstone Trail Marathon

The Yellowstone Trail Marathon, Half Marathon, 50K, 25K, and 10K races on August 1, 2026, offer an unparalleled trail running experience at the doorstep of the world's first National Park. Starting and finishing at the Rendezvous Ski Trails in West Yellowstone, Montana, runners will navigate mixed terrain, including trails, pavement, and gravel roads, winding through the breathtaking landscapes of the Custer Gallatin National Forest. The course promises awe-inspiring scenery, featuring national forests, blue-ribbon trout streams, and serene mountain lakes, providing an epic backdrop to your endurance challenge. Typical race day conditions in early August bring pleasant highs around 79°F and lows around 40°F, with only a 5% chance of precipitation.

Prepare for a challenging yet rewarding journey across rolling terrain and significant elevation gains. The marathon covers approximately 1,900 feet of elevation gain over a two-loop course, while the 50K boasts around 2,090 feet over two loops. The 25K features roughly 1,045 feet of gain in a single loop, and the 10K presents about 340 feet of climbing. Runners consistently describe the course as "unbelievable" with "unreal scenery," making the demanding hills and high altitude "worth every hard hour". Aid stations, equipped with water and Hammer Nutrition products, are strategically placed at the start, finish, and roughly halfway through each loop to support your effort.

This event is more than just a race; it's a "true running experience" fostering a strong sense of camaraderie among participants. While the stunning wilderness offers incredible views and the chance to spot local wildlife like bears, moose, and bison, carrying bear spray is strongly recommended by the Forest Service for your safety. Embrace the challenge and immerse yourself in the natural grandeur of West Yellowstone for an unforgettable running adventure.
