Next Equinox Challenge to be held in 2016

The Equinox Snow Challenge is a unique endurance event open to competitors of ALL AGES AND ABILITIES who wish to explore themselves, their limits, and cheer on their neighbor.  

The Equinox Ski Challenge was held at West Yellowstone on March 22nd + 23rd, 2014.  
The Equinox Fatbike Challenge also was in West Yellowstone on the same dates, using the same start/finish, and on an entirely separate course from the skiers.
