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.

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 halfregistration@baa.org concerning your request, and your registration will be updated accordingly. Please allow sufficient time for the correction to be made.

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.
