The Mammoth Half Marathon carries runners over a breathtaking, scenic course through California’s picturesque High Sierra mountains and operates under permit on 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!
