On Sunday, about 50,000 runners and their guests will pound the pavement during the TCS New York City Marathon, an economic juggernaut for the Big Apple.
So, just how much of an financial boost will the 26.2 mile race mean for the city?
Last year, it generated an economic impact of about $415 million, according to a report produced for race organizer New York Road Runners by AECOM, a firm that provides professional and technical services. A record 50,530 runners from 130 countries completed the 2014 marathon while roughly 258,000 guests visited the city during marathon week.
The city garnered another $22.2 million in sales and occupancy taxes from the marathon, which sprawls across all five boroughs.
Since it began in 1970, the race has grown exponentially from a race pool of just 127 entrants, less than half of whom were able to finish.
The NYC marathon is the world's largest marathon.
Last year, the distance saw a record number of finishers with about 550,000 runners completing it in the U.S. The number of marathons also hit a record with more than 1,200 events.
