Runners start the out-and-back course for the Yellowstone Half Marathon at the old airport along the western edge of West Yellowstone, which lies next to Yellowstone National Park. (The race start lies less than a mile from the western entrance to the park.) From there, they’ll head through the city and past the Grizzly & Wolf Discovery Center out into the Gallatin National Forest, where they’ll run mostly on dirt roads and trails.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
