Hosted by the Falmouth Running Club, the Cape Cod Marathon Weekend celebrates the beauty of the region with races for every level. Saturday features the fast and scenic half marathon along Vineyard Sound, while Sunday brings the certified, Boston-qualifying full marathon, alongside a 5K, marathon relay, and two multi-distance challenge options. Runners enjoy ocean views, charming New England towns, and rolling coastal roads—including the iconic Nobska Lighthouse stretch—on largely flat USATF-certified courses. The weekend also includes a lively expo, aid stations, timing, and environmental initiatives, with open but monitored traffic conditions. This beloved fall festival combines performance, participation, and picturesque Cape Cod charm.
