Tough Mudder will launch a new series in 2017, dubbed Toughest Mudder. It’s easy to see why the endurance event company selected Chester County’s Brandywine Valley in Pennsylvania as host of one of six regional eight-hour overnight races. Home2 Suites by Hilton Downingtown and a new Residence Inn by Marriott recently opened in the valley. Main Line Sports Center, a new indoor training facility targeting lacrosse practices and tournaments, is also a welcome addition for a region that distinguishes itself from Philadelphia. The addition of new venues has built a reputation to land Toughest Mudder, a weekendlong event including coverage from CBS Sports Network. Tough Mudder and Tough Mudder Half events will also be part of the intense action.
