Join this unofficial relay race through Boston's iconic Common, hosted by Endorphins Running and New Balance, where four-person teams take turns running the historic one-mile loop as the sun dips below the skyline. You can either bring your own crew or register solo to be matched with runners from different clubs, and you'll have multiple ways to compete for prizes—from fastest overall time to best team spirit. After the race, stick around to celebrate with fellow runners and swap stories at an after-party.
