Presented by Brigham and Women's Hospital, the 11th Annual B.A.A. 10K is the perfect way to kick off the summer racing season. As the second race in the B.A.A. Distance Medley, the 10K is scheduled for June 23. This race through the heart of Boston along Commonwealth Avenue is one of the most exciting in the area. In 2016 Massachusetts native Shalane Flanagan set the American women's 10K record on this course!
