Frequently Asked Questions

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.


Timing will stop six hours after the last person crosses the starting line in Hopkinton. The course will close at various intervals before that time.


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.


Your qualifying time is based on your age on the day of the Boston Marathon, thus your qualifying standard will be 3hrs 25 min - and you can be 44 when you run your qualifying race.

There is no waiting list for the Boston Marathon. Once it is announced that registration is closed, we are no longer able to accept entries.

B.A.A. Moment 1

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.
