Preparing for the Olympic Marathon later this summer, Flanagan motored her way to a time of 30:52, shattering both the national and event records. For the men, Daniel Chebii of Kenya won his American road racing debut in 27:55. In total, 7,805 participants finished this year's B.A.A. 10K, the largest in event history. The B.A.A. 10K, presented by Brigham and Women's Hospital, is an IAAF Bronze Label road race.
