On the heels of last week's deadly truck attack, New York city officials significantly increased security for Sunday's marathon, which was expected to attract tens of thousands of of competitors and spectators. Along the 42-kilometre route, New York police deployed extra "blocking trucks" to protect against vehicle attacks, rooftop snipers, heavy weapons, dogs and helicopters. New York Police Department officers take part in security screening before the start of the marathon. Trucks and police cars are used as barricades for the New York City Marathon. The marathon route connects all five of the city's boroughs, starting near the Verrazano-Narrows Bridge in Staten Island, snaking through Brooklyn, Queens and Manhattan, before circling up to the Bronx and back to Manhattan.
