Runners follow a point-to-point course through the High Sierras in the shadow of nearby Mammoth Mountain at the Mammoth Half Marathon, which starts at Horseshoe Lake and finishes along Old Mammoth Road, next to the Sierra Nevada Resort and Spa. In between, runners will make their way along a combination of trails and mountain roads, and the course includes stretches around Lake Mary and across the Waterford Bridge — starting at an elevation of about 9,000 feet above sea level.
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.
