epsom derby

The Derby Stakes, also known as the Derby or the Epsom Derby, is a Group 1 flat horse race in England open to three-year-old colts and fillies. It is run at Epsom Downs Racecourse in Surrey on the first Saturday of June each year, over a distance of one mile, four furlongs and 10 yards (2,423 metres), or about 1½ miles. It was first run in 1780. It is Britain's richest flat horse race, and the most prestigious of the five Classics. It is sometimes referred to as the "Blue Riband" of the turf. The race serves as the middle leg of the historically significant Triple Crown of British horse racing, preceded by the 2000 Guineas and followed by the St Leger, although the feat of winning all three is rarely attempted in the modern era due to changing priorities in racing and breeding, and the demands it places on horses. The name "Derby" (deriving from the sponsorship of the Earl of Derby) has been borrowed many times, notably by the Kentucky Derby in the United States, and to describe many other key racing and sporting events.
