Unfortunately, Boston Marathon bib numbers and entry fees cannot be refunded. Regrettably, we do not allow deferment of race entry to another year. Runner bib numbers cannot be transferred to another participant, and you may not give your number to someone else. The Boston Marathon is a top-level sporting competition, and the B.A.A. seeks to uphold the integrity of both its entrants list and field and the results and awards reports and rankings.

Refunds or deferments of bib numbers for the Boston Marathon will not be granted for any reason, including injury, pregnancy, military exercise or deployment, and family emergencies. We regret that we cannot make exceptions.

For active duty military deployments to war zones, deferment of qualifying times will be honored for a later race. However, there will be no refund or deferment of bib numbers or entry fee. The B.A.A. appreciates the understanding from all who ask this question of the race organization, and we appreciate the cooperation in upholding the policies that are in place.


Information Centers are located in the following locations during race weekend:

  • John B. Hynes Convention Center
  • Copley Square
  • Hopkinton Athletes’ Village
  • Stuart Street in Boston’s Back Bay

All of the above information is subject to change

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.


While it is popular belief that in 1887 the B.A.A. founders chose the Unicorn as the organization’s symbol due to its place in mythology (Chinese and other mythologies regard the figure as an ideal and something to be pursued but which can never be caught), it is more likely that the Unicorn was borrowed from the coat of arms from one of the B.A.A.'s first families. Still, the now iconic Unicorn stands for striving for excellence.... even it can never be achieved.


Race participants can check belongings at a designated location near the start. Belongings must be claimed shortly following the race. The B.A.A. is not responsible for personal belongings.

1966 - Bobbi Gibb

Although not an official entrant, Roberta “Bobbi” Gibb became the first woman to run the Boston Marathon. Joining the starting field shortly after the gun had been fired, Gibb finished the race in 3:21:40 to place 126th overall. Gibb again claimed the “unofficial” title in 1967 and 1968.
