Welcome to the Equinox!

Location and date TBD for 2016 Equinox Challenge

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.  

Equinox Ski Challenge and the Equinox Fatbike Challenge have been held bi-annually in West Yellowstone since 2007, traditionally run concurrently on separate courses while sharing a common start/finish area.
