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.

1920 - Ashland Start

The Boston Marathon began in Ashland, Massachusetts from 1897 through 1923 then moved to Hopkinton for the 1924 race. The course was lengthened to 26 miles, 385 yards to conform to the Olympic standard, and the starting line was moved west from Ashland to Hopkinton. Since then, the race has started in Hopkinton every year.
