Yellowstone Trail Marathon and Trail Races

Embark on an unforgettable journey at the Yellowstone Trail Marathon and Trail Races, set against the stunning backdrop of West Yellowstone, Montana, on July 11, 2026. This spectacular event offers distances for every ambition, including a 50K, Marathon (26.2M), 25K, Half Marathon (13.1M), 10K, and 5K, all commencing from the Rendezvous Ski Trails. Nestled just outside the west entrance to Yellowstone National Park and within the breathtaking Custer Gallatin National Forest, runners will experience a truly unique trail adventure amidst majestic mountains, pristine lakes, and vibrant forests.

The course presents a challenging yet rewarding mix of trails, pavement, and gravel roads, featuring uneven ground and loose stones. Prepare for significant elevation gains, with the 50K tackling around 2,090-2,200 feet, the 25K/Half Marathon ranging from 960-1,112 feet, and the 10K offering approximately 340-400 feet of ascent. Running at elevations around 6,000 feet requires runners to be mindful of altitude, and staying hydrated is key. Aid stations are strategically placed at the start, finish, and roughly halfway through each loop, offering hydration and Hammer Nutrition products, though carrying personal water is recommended for some distances. Typical race day conditions in July see highs around 77°F and lows near 39°F, with a minimal 5% chance of precipitation. Be bear aware, as wildlife encounters are possible in this region; carrying bear spray is strongly recommended by the Forest Service.

Participants consistently describe this Wolf Pack Adventures event as an "epic" and "unbelievable course," offering a true running experience amidst unparalleled scenery. The well-marked routes ensure an immersive journey through nature, while the supportive atmosphere and top-notch volunteers contribute to a memorable race day. Whether you're chasing a new personal best or simply seeking an extraordinary run in a wild setting, the Yellowstone Trail Marathon and Trail Races promise an unforgettable challenge and stunning vistas at every turn.
