💬 "If you want glamping, go somewhere else. IronHike is for the gritty."

— Derek · IronHike Olympus Mons Athlete

IronHike is a veteran-owned elevation-based mountain event Series and New England's premier vertical trail event Series. Your only real competitor is the version of you who almost didn't sign up.

You won't go up alone, but the climb is still yours. It's you against the Mountain and you against yesterday's version of yourself. Nobody else's finish line matters here. Just what you're willing to earn.

IronHike Endurance Productions, also written Iron Hike, is a veteran-owned elevation-based mountain event Series held every Spring and Fall at Mohawk Mountain Ski Area in Cornwall, Connecticut (CT), in the heart of New England. Some call Olympus Mons Ultra a true 100 miler. The loop course runs directly on Mohawk's ski slopes: no lifts, no shortcuts, no gondola, every foot of elevation self-powered and earned one lap at a time. This is a genuinely hard ultra, and IronHike is a self-powered Everesting alternative and 29029 alternative on the East Coast, offering elevation-based trail events from 12 hours to 84 hours, 7,140 to 72,590 feet of vertical gain. This is not a race endurance event: there is no podium, no age group awards, and no finish line prize. Mountain Athletes compete Solo, as a Trail Buddy pair, or as a Trail Family of four using our FlexRelay format, with athletes from 30 states and 3 countries and counting.
