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.
