BOSTON — Next year’s Boston Marathon has also been postponed.

The Boston Athletic Association said Wednesday it won’t hold the race as scheduled in April because of the COVID-19 pandemic. Organizers said it will be put off “at least until the fall of 2021.”

This year’s marathon was initially postponed until the fall and later canceled outright. It was to be the 124th edition of the world’s oldest and most prestigious annual 26.2-mile race.

The B.A.A. said it is working with government officials and others involved in the race to see if a fall 2021 date is feasible. Organizers said they are hoping to announce a date for an in-person race before the end of this year.
