Marathon

The Chicago Marathon, scheduled for October 11, has been cancelled due to the Covid-19 pandemic. It's the second time the marathon won't take place, with the last cancellation happening when Beatrice Foods withdrew its support in 1987.
"Our highest priority has always been the safety of our participants and our volunteers. We understand the disappointment, but when we return to the streets of Chicago, it will be a celebratory moment and an uncompromising statement about the collective spirit of who we are as a running community: We are powerful, we are persistent, and we will reach the finish line again," so Carey Pinkowski, race director of the marathon.

The 2020 New York City Marathon has been officially cancelled. The event was scheduled to take place November 1 and would have been the 50th running of the marathon. That will now happen on Nov. 7, 2021.
The organizers New York Road Runners and the city have decided and announced that the Covid-19 risk is too significant and therefore cancelled the marathon from happening.

During a news conference, Boston Mayor Marty Walsh announced the 2020 Boston Marathon has been cancelled for the first time in the event's history.
The Boston Athletic Association has determined that the traditional one day running of the 124th Boston marathon will not be feasible this year, given the Covid-19 pandemic.
The event was already postponed from April 20 to Sept. 14.
