Colt State Park Half Marathon

The Colt State Park Half Marathon is an intimate late-fall 13.1-mile race set entirely within Colt State Park on the shores of Narragansett Bay in Bristol, Rhode Island. Known for its flat, waterfront paths and stone-lined entrance drive, the park offers one of the most beautiful running settings in the state. Field size is capped at roughly 400 runners, giving the event a friendly, low-key feel compared with larger marathons. It is open to the public and suits both competitive half-marathoners and recreational runners looking for a scenic autumn goal race. Because the race sells out due to the limited field, early registration is strongly encouraged. Participants can expect a well-marked course, water support and a relaxed community atmosphere in a picturesque bayside park.
