The Mammoth Half Marathon carries runners over a breathtaking, scenic course through California’s picturesque High Sierra mountains and the Inyo National Forest. The route starts nearly 9,000 ft above sea level at Horseshoe Lake and finishes in downtown Mammoth Lakes (~7,800 ft). Since our inaugural race in 2013, we have added a scenic loop around Lake Mary and brand-new Waterford bridge, making our world-class course even better!
