The New York City Marathon is an annual marathon that courses through the five boroughs of New York City. It is the largest marathon in the world, with 50,304 finishers in 2013. Along with the Boston Marathon and Chicago Marathon, it is among the pre-eminent long-distance annual running events in the U.S. and is one of the World Marathon Majors.
The race is organized by New York Road Runners (NYRR) and has been run every year since 1970, with the exception of 2012, due to landfall of Hurricane Sandy. 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 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.
