For application into the Boston Marathon, applicants must provide the name and date of the Marathon at which they qualified, and their official finishing time. The B.A.A. will verify all qualifying times before granting acceptance into the race.

Yes, the event will engage the U.S. Anti-Doping Agency (USASA), in accordance with the international Standards of Doping Control, to test selected athletes who earn prize money. Athletes who participate in the B.A.A. Half Marathon may be subject to drug testing in accordance with the USADA Protocol for Olympic Movement Testing (USADA Protocol). USADA will be responsible for conducting comprehensive drug testing, as well as the adjudication of positive findings. Athletes with positive drug test results will have their cases adjudicated according to the USADA Protocol and will be penalized, if appropriate, according to applicable IAAF or World Anti Doping Agency rules. Such penalties may include, but not be limited to, a period of ineligibility from competition, as well as disqualification from past competitions and cancellation of awards and prizes previously awarded. Any substance taken by an athlete is at his/her own risk and may result in a positive sample. BEWARE: some nutritional supplements, prescription, cold medicines and over-the-counter medications contain prohibited substances. Information regarding specific drugs and substances may be obtained by calling the USADA Drug Reference Line at 1-800-233-0393, or by visiting www.usantidoping.org or www.888athlete.org.
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.

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.

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.
