California’s Eastern Sierra

42nd Annual Mammoth Marathon 42k

This 42nd annual cross-country ski event offers distances from 5–42km and is open to both classic and skate skiing. Join the fun and sign up to race, or come ring your cowbells and cheer on the sliders as they cruise around the Mammoth Lakes Basin. Tracks will be open to non-racers (with a valid ticket/season pass) during all races. Volunteers are always appreciated.
