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.

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.


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.

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.

1920 - Ashland Start

The Boston Marathon began in Ashland, Massachusetts from 1897 through 1923 then moved to Hopkinton for the 1924 race. The course was lengthened to 26 miles, 385 yards to conform to the Olympic standard, and the starting line was moved west from Ashland to Hopkinton. Since then, the race has started in Hopkinton every year.
