B.A.A. 10K : Boston Athletic Association
The B.A.A. 10K, presented by Mass General Brigham Cancer Institute, is scheduled for June 21, 2026. The event fields about 10 km of road racing through Boston, passing through Back Bay and Cambridge.
The race starts and finishes adjacent to Boston Common. The route runs along the Charles River, goes through Kenmore Square, and crosses the Boston Marathon finish line. The event attracts professional athletes at the front of the field and includes para and adaptive eligibility, divisions, and classifications.
Open registration for the event has closed, though some entries remain available through Mass General Brigham’s team. The race organizes spectator guidance, volunteer opportunities, and media relations for race day.
Recent event figures from 2025 are provided as context: 7,633 total finishers, participants from 97 countries, 600 runners on Mass General Brigham’s team, and $350,000 raised by that team. The organizer publishes athlete information, para and adaptive details, and resources for spectators and volunteers. Visit the organization's website for the most recent information.
