The Belmont Stakes 2018 was run at a mile and five furlongs from 1867 to 1873; a mile and a half from 1874 to 1889; a mile and a quarter in 1890, 1891, 1892, 1895, 1904 and 1905; a mile and a furlong in 1893 and 1894; a mile and three furlongs from 1896 to 1903 and from 1906 to 1925. The current distance of a mile and half was established in 1926.
The first post parade in the United States was at the 14th Belmont, in 1880. Before 1921, the race was run in the clockwise tradition of English racing. Since then, the race has been run in the American, or counter-clockwise, direction. Because of its length (one lap around the enormous Belmont main track), and because it is the final race of the Triple Crown, it is called the "Test of the Champion". Most three-year-olds are unaccustomed to the distance, and lack the experience, if not the stamina, to maintain a winning speed for so long. In a long race such as the Belmont, positioning of the horse and the timing of the move to chase for the lead can be critical.
