Join Yellowstone Half Marathon 2025
Get ready for the demanding Yellowstone Half Marathon, a thrilling trail race just outside the boundaries of Yellowstone National Park. Spanning 21.1 km (13.1 miles), this course begins and ends on Old Airport Road in West Yellowstone, leading you into the stunning Custer Gallatin National Forest. Athletes will tackle technical dirt trails filled with loose rocks, tree roots, and challenging ascents—perfect for those looking to push beyond traditional pavement races. Experience the thrill of potential wildlife sightings and breathtaking forest panoramas as you race through Montana's wild terrain. For those seeking a shorter challenge, a 5K race takes place the evening before. The event features a 4-hour time limit, making it accessible for walkers who can maintain an 18.5-minute mile pace. Prioritize trail-specific training to conquer this demanding course. Please note, the route is approximately 24 miles (39 km) from the national park’s iconic landmarks, offering an equally impressive natural backdrop.
