BOSTON — Boston Mayor Marty Walsh on Tuesday left the door open to making additional changes to the Boston Marathon, which was already rescheduled once, because of the coronavirus health crisis.

The 124th running of the world’s oldest and most prestigious marathon that was originally set for April 20, Patriots' Day. In March, officials rescheduled it for Monday, Sept. 14.

"When we originally made the decision to postpone the marathon to September, we were all very hopeful that the coronavirus would no longer be a significant public health risk for our residents," Walsh said Tuesday outside City Hall. "We are continuing to have right now a conversation with the BAA on the best way for all of us to move forward."

Walsh told reporters he had no "specific updates" to share about the ongoing talks.

The race generally draws more than 30,000 runners from all over the world, ranging from decorated professionals and Olympians to amateur runners who take to the storied 26.2-mile course through eight communities to raise money and awareness for charities.
