It is run at Doncaster over a distance of 5 furlongs and 143 yards (1,137 metres), and it is scheduled to take place each year in September. The event was established in 1855, and for a period it was known as the
Irish St. Leger 1915, and it was originally restricted to three-year-olds. The first horse to win both the English and Irish St Legers was Royal Lancer in 1922. The first Irish St. Leger winner to complete a Triple Crown (having previously won the Irish 2,000 Guineas and the Irish Derby) was Museum in 1935. The only subsequent horse to win all three races was Windsor Slipper in 1942. The Irish St Leger became an open-age race in 1983, and there have been several repeat winners since then. The most successful has been Vinnie Roe, with four consecutive victories from 2001 to 2004. The
