Participants in the B.A.A. Half Marathon will have their bib numbers mailed to them in advance of the race. Please remember to bring your bib number with you on the day of the event. If you have not received your bib number within one week of the event, please contact the B.A.A. at halfregistration@baa.org.

Please handle your bib with care. Your timing device will be attached to the back of your bib, and if it's bent too much, it will not record your time along the route.  


Registrants of the B.A.A. Half Marathon should receive their bib number in the mail. If you do not receive your bib number by one week prior to the event, send a detailed e-mail to halfregistration@baa.org. You will be provided a replacement bib which you can pick up on site at Franklin Park. If you are changing your address between now and the B.A.A. Half Marathon, please let the B.A.A. know, so your bib number is sent to your correct location.

Bring a government issued photo I.D. to the registration area on race day, and we will issue a new number. We will cancel your previous number, and void the timing device so that no one can misrepresent you.

If your Number Pick Up Card does not reach you before race weekend, please be sure to bring a photo ID with you to Number Pick-Up at the John Hancock Sports and Fitness Expo located at the Hynes Convention Center. Go to the "Replacement Number Pick-Up Cards" booth near number pick-up, show your valid photo id, and a volunteer will print a new card for you. You will use that new card to pick up your number. We are requiring that all participants claim their own bib number at the John Hancock Sports & Fitness Expo during normal expo hours. Friends or family will not be allowed to claim your bib number for you.

A complimentary ticket is included with your bib number packet. A limited number of additional tickets for both the pre-race dinner and post-race party may be purchased at the “Party Tickets” Booth when you pick up your number. Tickets will NOT be available for sale on site at either event.


Just keep moving through the finish area. Your medal will be awarded to you with your water and post-race refreshments.


The BibTag timing system will enable you to receive your official time (time from the starter's gun), as well as your net running time. The BibTag is affixed to your bib number and must be worn on your outer layer for the entire race for you to be scored and timed and for you to appear among the results as an official finisher. Please handle the tag with care, as bent or damaged tags may not work correctly.



Just keep moving forward! We'll get you your medal at the same time we get you your mylar blanket, water, and other post-race refreshments.


Free shuttle services, the MBTA, and our drop-off/pick-up location are your best bet. There will be no parking at the event location. Parking in the Jamaica Plain neighborhood is extremely limited, but some spots along the street may be available. For more details on our transportation program, click the button below:

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.

Born in West Medford, Massachusetts as one of ten children, Kelley ran track and cross-country at Arlington High School in Massachusetts. He did not finish his first Boston Marathon in 1928, but eventually competed in a record 61 Boston Marathons. A legend of the marathon, Kelley won the 1935 and 1945 runnings of the Boston Marathon. He finished in second place at Boston a record seven times. Between 1934 to 1950, he finished in the top five 15 times at Boston, consistently running in the 2:30s. He ran his last full marathon at Boston in 1992 at the age of 84, his 61st start and 58th finish there.
