Yes, it did. For most of the twentieth century, the Derby was run on Epsom Downs on the first Wednesday in June. The race was staged on a Tuesday between 1915 and 1918 and on a Saturday between 1942 and 1945, when run, as the ‘New Derby’, at Newmarket, and on a Saturday again between 1947 and 1950, and in 1953, following its return to Epsom Downs. However, in the face of dwindling attendances, the last Derby to be run in its traditional Wednesday slot was the 1994 renewal, won by Erhaab, and since then the race has been run on a Saturday afternoon. The move was not universally welcomed and was subsequently described by various commentators as ‘a mistake’ or even ‘a catastrophic blunder’. Nevertheless, at one point, in the face of declining TV audience figures, a Saturday evening slot for the premier Classic was mooted by the racecourse executive at Epsom Downs.
In 1779, Edward Smith-Stanley, 12th Earl of Derby founded a sweepstakes race, for three-year-old thoroughbred fillies, to be run over a mile-and-a-half on Epsom Downs. He called it the Oaks Stakes, after his nearby residence, known as ‘The Oaks’ or, historically, as ‘Lambert’s Oaks’, in Carshalton. Derby won the inaugural running of the Oaks Stakes with his own horse, Bridget, and subsequently celebrated with friends, who included Sir Charles Bunbury, Chairman of the Jockey Club.
Together, the pair co-founded another sweepstakes race, for three-year-old colts and fillies. Legend has it that they tossed a coin to decide on the name of the race but, in any event, the inaugural ‘Derby Stakes’ was run, over a straight mile, on Epsom Downs on May 4, 1780. Bunbury had some consolation insofar as he won the race, with Diomed, and collected the princely sum of £1,065 15s. The Derby Stakes was run over a mile until 1784, when the distance was extended to a mile-and-a-half and the sweeping, downhill turn into Tattenham Corner was introduced.
A thoroughbred racehorse typically gallops at around 30 miles per hour, on average, but, according to the Guinness Book of World Records, the fastest speed ever recorded was 43.97 miles per hour, by Winning Brew, a two-year-old filly, who covered two furlongs at Penn National Race Course, in Pennsylvania, USA in 20.57 seconds on May 14, 2008. Of course, the minimum distance over which thoroughbred horses race, in Britain, is five furlongs; the record over that distance belongs to Stone Of Folca, a four-year-old gelding, who achieved an average speed of 41.9 miles per hour when winning at Epsom Downs Racecourse, in Surrey, UK on June 2, 2012, in a time of 53.69 seconds.
