Registration for the Boston Marathon typically opens in early September, approximately seven months before the race. The B.A.A. uses a process to register runners which allows the fastest qualifiers in their gender and age group to register first.


The qualification window for the 2017 Boston Marathon opened on September 19, 2015.


Historically, runners who beat their qualifying standard by a larger amount of time are more likely to be accepted into the Boston Marathon. Since our rolling registration procedure was introduced in 2012, a cutoff has occurred 3 times:

  • Due to the high volume of applicants in 2012, the acceptance cutoff was drawn at 74 seconds. 
  • In 2013, we were able to accept all qualified runners who registered during the qualified registration period, so there was no cutoff time. 
  • In 2014, the cutoff for qualifying times was drawn at those who beat their qualifying standard by 98 seconds or faster.
  • The cutoff for the 2015 Boston Marathon was drawn at 62 seconds. 

Although these were the cases for previous years, we cannot predict how competitive the registration process will be for any given year, or how quickly it will fill. If you don’t have a qualifying time but still wish to participate, you can apply to run of one of the B.A.A. official charities by contacting them directly.

Registration for the Boston Marathon typically begins in the Fall prior to the race. We cannot predict how quickly registration will fill, but once it does, we are no longer able to accept registrations. The date that we close registration, therefore, becomes the deadline for qualifying.


If you feel there is a discrepancy in your 2015 Boston Marathon finish time, please use the following link to submit a Results Adjustment Form by no later than Thursday, April 30th:

We will look into every adjustment request we receive through Thursday, April 30th. Please note that the adjudication process can take up to a month to complete.

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