Mammoth Half Marathon & 5K

You’ll start this stunningly picturesque race through Northern California’s High Sierras at roughly 9,000 feet above sea level, and follow a route that runs along a combination of trails and mountain roads, including stretches around lakes and across a bridge at the Mammoth Half Marathon, set for its annual running this year.

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. 

Elite runners, including current and former Olympians, take advantage of training in Mammoth’s picturesque scenery and high altitude to prepare for their season. Follow in the footsteps of world-class elite runners and discover the town of Mammoth Lakes, California, located in the heart of the Eastern Sierra Mountains! Mammoth Lakes is home to one of the country’s top ski and snowboarding resorts in the winter and serves as an equally beautiful summer vacation destination. In addition, Mammoth Lakes is only a 45-minute drive to Yosemite National Park.
