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 going to be the best damn weekend of your year.
3 Miles, 10 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 and selected by our crew of genius engineers for max levels of fun and intense teamwork. None does it better than our massive finisher obstacle Happy Ending, presented by Merrell, a slippery juggernaut of epic proportions that requires real teamwork to conquer. That means even if you arrive alone, you’ll always finish Tougher Together. 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.
