OUR UNIQUE VISION

As a nonprofit 501(c)(3), the Mammoth Half Marathon benefits charity partners and community service projects, with 100% of our net proceeds going to local causes.

VISIT BEAUTIFUL MAMMOTH LAKES

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, located in the heart of the California’s 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.  Visit Travel & Hotels to book a room at one of our preferred hotels.

TAKE THE CHALLENGE

Finishers of both the 2018 San Diego Half Marathon and 2018 Mammoth Half Marathon will receive an extra-large “San Diego-Mammoth Challenge” spinner medal.  San Diego boasts over 70 miles of coastline, an average daily temperature of 70.5 ºF (21 ºC) and world-class attractions such as SeaWorld, San Diego Zoo, Safari Park, and Legoland California!
