There was a random selection component to the registration process for the 2015 B.A.A. Half Marathon when entries were accepted. The total field size for the event is 8,500 participants.

There were 2,640 runners pre-registered for the event though B.A.A. Distance Medley (B.A.A. 5K, B.A.A. 10K, and B.A.A. Half Marathon) registration held in January. An additional 700 runners will comprise the Dana-Farber Fundraising Team and each will raise at least $750 for the Jimmy Fund. Dana-Farber Cancer Institute and the Jimmy Fund have been the event's presenting sponsor since 2003. Once the elite field and other invitational entries were accounted for, this left approximately 5,000 entries available through online registration that opened on July 15.
