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.

The B.A.A. does not decide whether a qualifying race is certified or not. The race director or race management of that event can tell you if a course is certified. For a complete list of certified courses in the U.S.A. check USA Track & Field. In Canada check Athletics Canada. Internationally, an extensive calendar of races is listed at the Association of International Marathon and Road Races website, with indication of courses that are not certified.
If your Number Pick Up Card does not reach you before race weekend, please be sure to bring a photo ID with you to Number Pick-Up at the John Hancock Sports and Fitness Expo located at the Hynes Convention Center. Go to the "Replacement Number Pick-Up Cards" booth near number pick-up, show your valid photo id, and a volunteer will print a new card for you. You will use that new card to pick up your number. We are requiring that all participants claim their own bib number at the John Hancock Sports & Fitness Expo during normal expo hours. Friends or family will not be allowed to claim your bib number for you.

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.

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.
