Chatham in the Fall 10k Run 2026

The Chatham in the Fall 10K is a certified 10K road race held in Chatham, Massachusetts, starting from Monomoy Regional Middle School. This USA Track & Field sanctioned event is managed by the Cape Cod Athletic Club, with assistance from local businesses. Participants can run the entire 10K individually or form a 2 x 5K team relay. The race begins at 9:00 AM, with bib pickup and same-day registration available earlier. The course begins approximately two-tenths of a mile from the school and concludes back at the school for awards presented in the gym. Over 200 runners participate, including individuals, relay teams, club members, and local residents. All finishers get medals. Trophies are awarded to the top male and female overall finishers and the top three in each 10-year age category. The post-race gathering takes place at The Squire in downtown Chatham. Proceeds benefit Cape Cod Foster Closet, Sharing Kindness, Cape Cod Athletic Club scholarships, and the WCOD Stuff-A-Bus toy drive. Participants may also bring an unwrapped toy for the donation box at the event.
