Registration for 2021 Boston Marathon put on hold

Boston Marathon registration is on hold while organizers try to figure out how the race will need to change in the coronavirus era.

The Boston Athletic Association said Thursday that registration will not take place in September as scheduled. A new timeline will be determined by a COVID-19 advisory group that will help the B.A.A. decide when and how large in-person road races can be held safely. The group will be comprised of medical experts, public safety officials and representatives from the government.

The world's oldest and most prestigious annual 26.2-mile race, the Boston Marathon postponed its 124th edition from April to September because of the coronavirus pandemic. It was then canceled.

The 2021 Boston Marathon remains scheduled for April 19.
