Mayor Walsh said today he is "hopeful" the Boston Marathon can still be run on its rescheduled date of Sept. 14, but acknowledged that a marathon planned for later that month in Berlin was canceled yesterday because of Covid-19 concerns.

At a press conference outside Boston City Hall, Walsh acknowledged that even if the race can go on, there are still conversations needed to consider if the Marathon can be run anywhere near as normal, given that it usually involves tens of thousands of runners and spectators.

Walsh added that even as the city's economy slowly comes back to life as the current surge of Covid-19 infection eases, there's one business he expects to continue to be depressed for a long time: "I don't see tourism coming back for months if not another year or so."

Also today, city Health and Human Services Chief Marty Martinez said that, in addition to the increased Covid-19 testing at several Boston neighborhood health centers announced by Gov. Baker, he expects the centers to also begin offering antibody testing, once that becomes available. Both Baker and Walsh have said that both kinds of testing will be critical to fully re-starting the economy by trying to cut down the spread of the virus.

Walsh joined Baker in denouncing the president's tweeted immigration ban. Walsh called it "foolish," said immigrants make up large percentages of "essential" workers, including those in healthcare, and said Boston will continue to stand by its immigrant residents.
