Tarzan Brown Mystic River Run

Tarzan Brown Mystic River Run is held in Stonington, Connecticut, on November 7, 2026. The five-mile race (8 kilometers) starts at 10:00 a.m. and follows a scenic route along the Mystic River, starting and finishing on Pearl Street. A half-mile kids fun run goes off earlier at 9:30 a.m., free for children aged 10 and under who register in advance. Entry fees vary by age, which keeps the event accessible to a broad field.

Five miles is a distance worth racing on its own terms rather than as a short 10K: you can run it close to threshold effort from the first mile if your fitness supports it. A month of four runs a week with one tempo session prepares you well. Afterwards there is a celebration with food, drinks and an awards ceremony for the leading athletes.
