>> 50,000 people will run in the New York City marathon this Sunday and 2.5 million spectators will line the streets to cheer them on. An inspiring feat of human triumph, but a challenging security task, just days after a horrific truck attack in lower Manhattan killed eight people. NYPD stepping up security this year, saying they would deploy extra blocking trucks to protect against vehicle attacks.
As well as rooftop snipers, heavy weapons, dogs and helicopters. Still, runners remain undaunted by the threat. According to organizers of the annual race, they have not seen a spike in cancellations this year. As the world's biggest marathon, in a city that's been on heightened alert since September 11th, the NYC marathon is always heavily fortified.
The race has been cancelled only once in its 47 year history, in 2012 following superstorm Sandy's devastating hit to the region.
