Mammoth Winter Biathlon  |  March 20–21, 2020

The Mammoth Winter Biathlon has a history as being one of the community’s favorite events at the beautiful Tamarack Cross-Country Ski Center in the Mammoth Lakes Basin. The event combines cross-country skiing with rifle shooting in a safe, fun competitive race. All ages and abilities are welcome and encouraged to participate.

The 2020 Mammoth Winter Biathlon will be held at Panorama Dome, on the Dome and Vista trails of the Tamarack Cross-Country Ski Center. The venue is just 250m from the winter closure of Lake Mary Road, providing easy access for competitors and spectators. There will be a full range of events for all ages, from first-time beginners to experienced biathletes. Rifles will be provided.

There will be a "how to race a biathlon shooting clinic" held for youths and adults on Friday, March 20 followed by a day of biathlon races on Saturday, March 21.

Registration opens on January 15, 2020 and will close March 18, 2020 at midnight PST.
