B.A.A. 10K

Lace up for the B.A.A. 10K, a premier road race unfolding on June 21, 2026, through the historic streets of Boston, Massachusetts. Organized by the renowned Boston Athletic Association, this 10-kilometer event draws nearly 10,000 participants, from elite athletes to recreational runners, all united in a vibrant celebration of running. The flat, fast, and scenic course offers an unforgettable urban experience, starting and finishing adjacent to Boston Common on Charles Street. Runners will traverse Boston's iconic Back Bay, winding along the picturesque Charles River Esplanade, through bustling Kenmore Square, and making the memorable pass over the legendary Boston Marathon finish line on Boylston Street. While predominantly flat, the course does feature some gentle inclines, particularly along Commonwealth Avenue.

As a key component of the B.A.A. Distance Medley, the B.A.A. 10K boasts a reputation for excellent organization and a festive atmosphere. Typical race day conditions in late June bring highs around 78°F and lows around 62°F, with a 14% chance of precipitation, so runners should be prepared for potential summer warmth and humidity, especially on exposed sections of the course. Hydration is well-supported with water and Gatorade stations available at every mile from mile two onward, positioned on both sides of the road, along with portable toilets at each aid station.

Participants can expect a quality experience, including a distinctive adidas participant shirt and a coveted unicorn finisher medal, a symbol of the B.A.A.'s rich 139-year history. Beyond the personal challenge, the race serves as a fundraiser for Brigham and Women's Hospital, allowing runners to contribute to vital medical research and patient care. Join thousands of fellow enthusiasts for a truly unique Boston running tradition.
