In keeping with the history of the first marathon, running groups from all over the world organize races that are similar to the one Pheidippides ran. One of the top five marathons to compete in is the New York City Marathon. This race debuted in 1970, and is sponsored by New York Road Runners Club. The first running of the New York City marathon consisted of four loops around Central Park. Today the race course consists of all five boroughs. The race begins on the first Sunday in November. The starting line is in Staten Island at the base of the Verrazzano Narrows Bridge. After crossing the bridge and completeing the first two miles of the race, the course runs eleven miles through neighborhoods in Brooklyn.
