About this race
ARE YOU TOUGH ENOUGH?
Tough Mountain Challenge isn't your average obstacle race—it's New England's most rugged, rowdy, and relentlessly fun mountain challenge. Since 2010, participants have been conquering mud, mountains, and obstacles at Sunday River Resort in one unforgettable summer tradition.
The course winds through ski trails, wooded terrain, and natural mountain features, with plenty of custom-built obstacles designed to push your limits. Whether you're racing for a personal best, tackling the course with friends, or simply looking for an epic adventure, Tough Mountain Challenge delivers an experience you'll be talking about long after the mud washes off.
Mark your calendar for Saturday, July 24, 2027, and get ready to take on the mountain. See you at the starting line.
