We encourage all participants using the B.A.A. shuttles on the Boston common to load the shuttles that correspond with their wave assignments. However, you may load an earlier shuttle if there is room.

We cannot make hotel recommendations. The Greater Boston Convention and Visitors Bureau has an extensive list of hotels in the Greater Boston area. Additionally, Marathon Tours and Travel is an official partner of the Boston Marathon, and they have rooms on hold at many hotels in the City of Boston.
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.

As your qualifying time is verified, we may find that your name was misspelled, your zip code was wrong, or other minor mistakes with your application. As long as your qualifying time can be verified, these mistakes should not jeopardize your entry into the Boston Marathon. You will be contacted by the B.A.A. eventually to correct this information.


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.

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.
