(CNN) -- The New York City Marathon - scheduled for Sunday - was canceled Friday due to lingering effects from Superstorm Sandy, the city's mayor said.
Mayor Michael Bloomberg had said earlier in the week the race would go on - despite transportation, power and other issues - contending, among other things, that businesses could use the economic boost the event provides.
"This city is a city where have to go on," Bloomberg said Wednesday.
First held in 1970, the New York City Marathon now attracts about 47,000 runners and 12,000 volunteers - not to mention an estimated 2.5 million spectators who annually line the course, which goes through all five city boroughs.
While there has been significant progress since Sandy, large swaths of the city remain without power and public transit options remain limited.
