Course
Ted Corbitt helped plan the deceptively hilly course of the New York City Marathon. 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.
After descending the bridge, the course winds through Brooklyn for approximately the next eleven miles (18 km). Runners pass through a variety of neighborhoods, including: Bay Ridge, Sunset Park, Park Slope, Bedford-Stuyvesant, Williamsburg, and Greenpoint. At 21.0975 kilometres (13.1094 mi), runners cross the Pulaski Bridge, marking the halfway point of the race and the entrance into Long Island City, Queens. After about two and a half miles in Queens, runners cross the East River on the Queensboro Bridge into Manhattan. It is at this point in the race when many runners begin to tire, as the climb up the bridge is considered one of the most difficult points in the marathon.
Reaching Manhattan after about 16 miles (26 km), the race proceeds north on First Avenue, then crosses briefly into The Bronx via the Willis Avenue Bridge for a mile before returning to Manhattan via the Madison Avenue Bridge. It then proceeds south through Harlem down Fifth Avenue and into Central Park. At the southern end of the park, the race proceeds across Central Park South, where thousands of spectators cheer runners on during the last mile. At Columbus Circle, the race re-enters the park and finishes outside Tavern on the Green. The time limit for this course is 8½ hours from the 10:10 a.m. start.
In 2008, the race initiated a corral system. Women were given a head start and the balance of the runners began in three staggered starts. The official times are those recorded by a computer chip worn on the shoe, which calculates when a runner crosses the start and when she crosses the finish, known as "net", as opposed to "gun", time. Runners also pass timing mats at 5 km intervals along the course and email notifications can be received by people following runners during the race to see how the runners are doing. In addition, while the distance is the same, there are different courses taken through Bay Ridge and up Fourth Avenue in Brooklyn until the course reaches Lafayette Avenue in Brooklyn at Mile 8.
Although the marathon publicity material uses miles, the timing mats are at 5 km intervals to accommodate the publishing of splits and also enabling potential world records for 20 km, 30 km and other sub-marathon distances to be recorded.
