While the B.A.A. discourages the use of iPods and headphones, we do not impose a ban on wearing such devices in the Boston Marathon except for the elite men and women and all those eligible for prize money. Many runners choose not to wear headphones, and instead listen to the crowd cheer them to Boylston Street.

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.
Please send a detailed email to registration@baa.org describing your lost item(s). If we have received it, we will contact you.

Medical personnel will be available to give emergency care, as well as attend to non-critical injuries at miles 0.7, 2.0, 4.5, 7.5, 11.2, 12.0 and the finish.


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 you are interested in exploring sponsorship opportunities with the Boston Marathon, B.A.A. Half Marathon, or any B.A.A. event, please contact T.K. Skenderian at tk@baa.org.

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

Marathon Foto is the official photographer of the B.A.A. Half Marathon and representatives will take photos along the course and finish. Proofs will be mailed to all participants shortly after the race, or photos may be ordered on-line at www.marathonfoto.com.

No bags will be allowed on buses from Boston to Hopkinton, and bags will not be transported from Hopkinton back to Boston. Bags will not be allowed in certain areas at or near the start in Hopkinton, at or near the finish in Boston, or along the course. At the conclusion of the race, the B.A.A. will provide you with a Heatsheet® Warmth Retention Cape for warmth.

A gear check opportunity on Boston Common will be available on the morning of the Boston Marathon, allowing official participants to have a change of clothing (shoes, pants, shirt, jacket) at the conclusion of the race. The bag to be used for this purpose will be provided at Number Pick-up by the B.A.A. 

Only this B.A.A.-provided, clear, plastic bag can be used for this purpose. No other bags will be accepted. Any items that you would like to have with you at the conclusion of the race must be placed inside the clear, plastic bag that the B.A.A. will provide for you. You must leave this clear, plastic bag at the gear check area on Boston Common prior to boarding the B.A.A. shuttle bus to the start in Hopkinton. Please be aware that the gear check area on Boston Common is approximately one half mile from the exit of the finish area at Arlington Street.


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.  


B.A.A. Moment 2

1935 John A. Kelley

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.
