and 1 mile plus 145 feet). Some American racetracks have circumferences of more (or, generally in the case of minor-circuit tracks, less) than ; examples include Aqueduct, Arlington Park, Hollywood Park Racetrack and Saratoga, all of which are tracks, and Belmont Park, the country's largest track, with a circumference. The backstretch chutes at Aqueduct and Arlington Park are long enough to permit races to be run at , while Saratoga's chute is shorter, extending only to . Hollywood's chute formerly allowed races, but when its finish line was moved forward in the late 1980s races could no longer be accommodated, and became the longest distance that could be run out of its chute (an unintended consequence of this was that by the mid-2000s -furlong [1,509 m] dirt races had gained considerable popularity in the United States when such races had rarely if ever been run before at most tracks, even those where the track's configuration made it possible to do so). At Belmont, the chute permits races at distances up to to be run (formerly up to , but this chute, which at one point crossed over the training track, was truncated in the late 1970s to eliminate the aforementioned cross-over, and today dirt races at Belmont actually start on the clubhouse turn, the only situation where races do this at any major American track). Belmont's outer (Widener) turf course also contains two chutes which separate from the beginning of the backstretch at an angle; races at distances of and are started from these chutes. Rarely, a "half-chute" will be employed; in this instance, the chute will branch off from a turn, usually the clubhouse turn, at the midway point of the turn, and extend to a position level with that of the homestretch, the chute thus joining to the turn at a 90-degree angle. Currently only one racetrack of note in the United States — Ellis Park Racecourse in Kentucky — makes use of such a chute, starting races from it at the distance of one mile (Ellis Park is a 1 mile [1,811 m] track). Formerly, Saratoga also had such a chute; it was known as the "Wilson Mile" chute, and like the one found at Ellis Park, it was used to start races. Use of the Wilson Mile chute was suspended in 1972; after being reinstated briefly in the late 1980s and early 1990s, the chute itself
