TOUGH MOUNTAIN CHALLENGE
CAN YOU HANDLE IT? Since 2010, Tough Mountain Challenge has been New England’s go-to event for mud, sweat, beers, and bragging rights. It’s not about winning—it’s about showing up, getting filthy, and laughing your way through the pain with 3,600 other lunatics.
Think you’re tough? Prove it.
The next race is Saturday, July 26, 2025.
Win Big. Get Dirty First.
Sign up for the 2025 Tough Mountain Challenge and you’re automatically in the running for some seriously awesome prizes—including a brand-new camper, a 2025/26 New England Pass, and more.
Participants must be 18 years of age or older and present to win.
