We anticipate it taking no longer than 15-minutes for the last runner of each wave to cross the starting line.


Timing will stop six hours after the last person crosses the starting line in Hopkinton. The course will close at various intervals before that time.


The B.A.A. will broadcast every five kilometer split to its website and family and friends can track your progress by logging in and entering your name or bib number. The "face" of the Boston Marathon website will change on race day and the process on how to enter the search will be clear. The AT&T Athlete Alert program allows messages to be automatically delivered to any US mobile phone, a pager, or any email address.

Alerts will be broadcast when your runner crosses the starting line, reaches the 10K, half marathon and 30K marks, and from the finish line. Runners or their family and friends can register in three ways:

  • Via text message or SMS, (after registering, you'll receive a text message confirming how to complete registration).
  • Visiting the AT&T Athlete Alert Sign-Up page at the race website, www.baa.org, and sign up there.
  • Registering in person. Representatives will be available in the Bib Number Pick-up area at the John Hancock Sports & Fitness Expo.

Only officially registered participants are allowed on the course. The course and finish area facilities close six hours after the last runner crosses the starting line. The Boston Marathon does not have a race walk division.


The Boston Marathon starting line is located in Hopkinton at the Doughboy statue on East Main Street (near Ash Street). The race finishes on Boylston Street in Boston, directly in front of the Boston Public Library (700 Boylston Street).


Because of the four-wave start, we will be timing and scoring by net time, the time from when you cross the starting line until you cross the finish line. Prize money will be awarded by gun time, but the elite athletes are up front so their gun and net times are virtually the same. Age group awards are based on net time.


If you're planning to drive to Hopkinton, we advise that you arrive at the South Street Lot at least 45 minutes prior to your starting time. Please take potential traffic congestion into account and note that taking the B.A.A. shuttles is the ONLY way we can guarantee that you'll get to the Athletes' Village on time.

While there is no 'official charity' program for the B.A.A. Half Marathon like there is for the Boston Marathon, Dana-Farber Cancer Institute and the Jimmy Fund field a large team of runners every year who, through fundraising, help them further cancer research.


American Red Cross Aid Stations providing first aid/medical support are located approximately every mile along the race course, including one at the start. Medical areas will be set up to provide medical support at the finish area.

B.A.A. Moment 1

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.
