“The 127th Boston Marathon will be another significant moment in B.A.A. history, as we recognize and honor the tenth anniversary of 2013,” said Jack Fleming, Acting Chief Executive Officer of the B.A.A. “On the third Monday in April 2023, athletes from around the world will gather with the resilience and spirit that has distinguished the Boston Marathon as the premiere event in road racing.”

Registration will open on Monday, September 12 at 10:00 a.m. ET and will close on Friday, September 16, 2022 at 5:00 p.m. ET. The B.A.A. will use the same registration process for qualified runners as it used for the 2021 and 2022 races, allowing any athlete who has achieved a currently valid Boston Marathon qualifying time to submit a registration application between September 12–16, 2022 through the B.A.A.’s online platform, Athletes’ Village. Registration is not on a first-come, first-served basis and applications will be accepted until 5:00 p.m. ET on Friday, September 16. The 2023 Boston Marathon qualifying window began on September 1, 2021 and will close at 5:00 p.m. ET on Friday, September 16.

Qualifying standards for the 127th Boston Marathon can be found here. Qualifiers may submit an application at any point during the registration window. Achieving one’s qualifying standard does not guarantee acceptance into the Boston Marathon. Those who are fastest among the pool of applicants in their age and gender group will be accepted.

Entry fees and information on health and safety guidelines, including any COVID-19 policies, will be announced in the coming weeks. For the third straight year, participants will have the opportunity to purchase registration insurance at the point of registration.

The qualifying window for the 128th Boston Marathon, scheduled to take place on April 15, 2024, will begin on September 1, 2022. Registration details for that race will be announced following the 2023 Boston Marathon.
