Aqueduct Racetrack, known as the Big A, is a horse racetrack in the neighborhood of Ozone Park in Queens, New York. It was opened in 1894, and was rebuilt in 1959.
It is the one racetrack located totally within the New York City limits; with the exception of a small amount of its western perimeter, Belmont Park -- also operated by the New York Racing Association -- is located in Nassau County on Long Island.
The track itself has three courses: The Main Track (dirt) has a circumference of 1 1/8 miles; inside of this is the Inner Dirt Track (consisting of a special type of dirt over which races are run during the winter months), which is exactly one mile long; and the innermost course is a turf (grass) course, spanning 7 furlongs plus 43 feet. Before 1976, the Inner Dirt Track was a turf course and it was known as the Main Turf Course, with the lone present turf course bearing the name of the Inner Turf Course; following the conclusion of racing in 1975 the grass on the Main Turf Course was uprooted and the Inner Dirt Track took its place to permit year-round racing, which was implemented at that time (in the first few years after Aqueduct was rebuilt in 1959 the track lay idle from early November until April 1; by 1971 this period had been reduced to from shortly before Christmas until March 1, and in the latter year off-track betting began in New York City, creating a demand for horse racing to be contested there throughout the year).
Today a single meeting is held annually at Aqueduct; it typically begins on the last Wednesday in October and runs all the way through the first Sunday in May. Races are run on the Inner Dirt Track between the second Wednesday in December and the third Sunday in March in most years. Prior to 1977, a summer meeting was also conducted at Aqueduct, running from mid-June to the end of July. From 1963 through 1967, races normally run at Belmont Park (including the Belmont Stakes) were run at Aqueduct instead while Belmont's grandstand was being rebuilt.
Today few important races are run at Aqueduct, mainly due to the unfavorable weather conditions that prevail during its racing season; however the prestigious Jockey Club Gold Cup was run there through 1976, and what was perhaps the track's most distinctive race, the marathon, 2¼-mile Display Handicap, was last contested in 1990. The track did play host to the second ever Breeders' Cup, in 1985.
Every summer weekend, a flea market is run in the racetrack's north parking lot. Pope John Paul II said mass in front of a large crowd at Aqueduct in October, 1995.
