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.

Extensive calendars of marathons can be found at www.marathonguide.com, www.coolrunning.com, www.runnersworld.com, and www.runningnetwork.com See our list of the most frequently used marathons for qualifying.
Please send a detailed email to registration@baa.org describing your lost item(s). If we have received it, we will contact you.
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.

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.

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.
