The race is organized by New York Road Runners (NYRR) and has been run every year since 1970. The next marathon will be run on November 7, 2010. In recent years, it has been sponsored by the financial group ING. It is held on the first Sunday of November and attracts professional competitors and amateurs from all over the world. Because of the popularity of the race, participation is limited to 37,000 entrants chosen largely by a lottery system. Runners who are members of NYRR can gain entry by meeting the qualifications for guaranteed entry or via nomination from an official running club. Officially recognized running clubs are allowed two guaranteed spots for members who did not make it in via lottery.
The initial course of 1970 consisted in repeated racing around Central Park. Nowadays the course covers all five boroughs of New York City. It begins on Staten Island near the approach to the Verrazano-Narrows Bridge. The bridge, which normally carries only vehicular traffic, is closed for the event. Runners use both sides of the upper level of the bridge and the westbound side of the lower level. In the opening minutes of the race, the bridge is filled with runners, creating a dramatic spectacle that is closely associated with the event.
