B.A.A. 10K
The B.A.A. 10K is presented by Mass General Brigham Cancer Institute and takes place in Boston, with the 2026 edition scheduled for June 21, 2026. The race course starts and finishes adjacent to Boston Common, follows the Charles River, passes through Kenmore Square, and crosses the Boston Marathon finish line. The event is a 10 km road race that routes through Back Bay and Cambridge.
The field is large; the organizer notes 10,000 participants will take part on race day and open registration has closed, though additional spots remain on Mass General Brigham’s team. The event includes designated para and adaptive divisions with published eligibility and classification information. A professional athlete field is included, and free youth races for children up to 12 years old accompany the main race.
Additional event activities and services include spectator information, volunteer opportunities, and media relations. Recent event metrics from 2025 show 7,633 finishers, representation from 97 countries, 600 runners on Mass General Brigham’s team, and $350,000 raised by that team. The organizer provides athlete resources and specific guidance for para and adaptive competitors, spectators, and volunteers. Visit the organization's website for the most recent information.
