Half Marathon races near Westerly

The Block Island Half Marathon is an annual October half marathon on Block Island, Rhode Island, starting and finishing at Fred Benson Pavilion. This is a small island race, not a big-city road event, with the route utilizing the island's natural features as its primary attraction. Runners proceed through beach dunes, past the Great Salt Pond, and toward North Point Light before returning along the west side of the island. The Atlantic Ocean is visible during portions of the run. All finishers receive a medal, and those who pre-register also get a race T-shirt.

Ocean State Rhode Races is a running series in Rhode Island organized by Rhode Races & Events, featuring races and activities across the state. The broader Ocean State Multisport group, based in New England, organizes USAT and USATF sanctioned road races, triathlons, and duathlons. Their stated goal is to encourage more people to exercise and gain the confidence to participate in sanctioned events. The series functions as a tour of Rhode Island's cities and towns, rather than concentrating events in a single location. Participants can enter individual races or compete in three or more events to achieve Rhode Master status. The organizers also provide virtual events for those seeking a race-like objective from home. The merchandise reflects the local theme with "13.1 Run RI" and "26.2 Run RI" stickers, alongside race shirts for events like Newport, Bristol, and the Ocean State half marathon.
