While the 26.2-mile full marathon starts in the tiny town of Molt, just outside Billings, runners in the half marathon start their race at the midway point of the full marathon course, on Molt Road. From there, they follow the same course for the second half of the full marathon, first through the wide-open prairies outside Billings and later within the city, past a number of city parks and across bridges over creeks and rivers, as well as past the Yellowstone Country Club.
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.
