2026 B.A.A. Half Marathon

Race Information

The Boston Athletic Association (B.A.A.) Half Marathon, presented by Dana-Farber Cancer Institute and the Jimmy Fund, highlights the beauty of Boston and Brookline's Emerald Necklace park system while furthering the B.A.A. mission of promoting health and fitness. The 13.1-mile, out and back, rolling course, begins and ends at White Stadium in Boston's Franklin Park. The park, one of the oldest in America, is located in Boston's Jamaica Plain and Dorchester neighborhoods.

The B.A.A. Half Marathon serves as the 3rd race of the B.A.A. Distance Medley, a three race series that also includes April's B.A.A. 5K and June's B.A.A. 10K. Many of the world's fastest runners participate in the B.A.A. Distance Medley each year.
