The Lowdown

The Cape Cod Marathon Weekend — presented by Shipwrecked — closes out the New England fall racing season in Falmouth, Massachusetts, pairing small-town maritime charm with a serious marathon. The weekend runs across two days and seven events: the half marathon on Saturday, then the marathon, marathon relay, 5K and kids' fun run on Sunday, plus the two-day Lobstah and Clam Chowdah challenges. Everything starts and finishes at Mullen Hall School on Katharine Lee Bates Road, a few minutes from Falmouth village. The marathon field is capped at the first 1,200 runners, and the 2026 edition sold out ahead of race day. The course is a fast, scenic route that hugs the Falmouth coastline of Nantucket Sound, staged to maximize the views of Martha's Vineyard across the water. The remaining miles wind through village centers and tree-lined residential roads in full autumn color. It is USATF-certified (MA23007JK) and a Boston-qualifying course, run under a six-hour limit with the course closing at 2:00 pm. Aid stations along the route, a large local volunteer crew, and waterfront spectators give race day the feel of a town event rather than a big-city marathon.
