"We know this is a challenging time for everyone, and the cancellation of the NYC Half is disappointing news to many, but the resources necessary to organize an event with 25,000 runners on the streets of Brooklyn and Manhattan have become strained during this difficult period," New York Road Runners said in a statement.
NYRR said that it was hoping to move forward with the March 15 race by finding ways to ease crowding and "facilitate social distancing" to minimize the risk of transmission of the virus.
"Unfortunately, it has become clear that we will be unable to proceed in the manner that our runners have come to expect at NYRR events, where the safety and security of our runners, volunteers, staff, partners, and spectators are our main concern," the organization said.
New York Road Runners said it will offer registered runners either a full refund or a guaranteed spot in next year's race. Runners who pick the latter option would have to pay the entry fee again.
