Event Overview
A New Breed of 5K
Tough Mudder 5K Boston; the only 5K mud run where the obstacles are friggin’ huge and the wicked good times never stop. Our obstacle-crushing fun run is located at 508 International, a short drive from Boston proper. It’s the best place to let loose and get wild this season, and it’s jam-packed with woods, trails, and tons of mud. Tough Mudder 5K Boston is gonna be wicked pissah.
3 Miles, 13 Iconic Tough Mudder Obstacles
This ain’t your grand-daddy’s fun run. Tough Mudder 5K Boston is 3 miles of best-in-class obstacles, designed for intense teamwork and fun. None does it better than our most iconic obstacle, Everest 2.0, a 13' quarterpipe with curved top that requires real teamwork to conquer. Bust through the finish line and the party keeps going. Grab a frosty cold beer, listen to music, hang with your new best friends from course, and soak in that sweet first taste of Tough Mudder.
