With perhaps 200,000 people, including the Prince of Wales, watching, the eighty-seventh running of the Derby took place at Epson in England. The favorite, Lord Lyon, ridden by Harry Custace, won a relatively slow race, coming from behind on the final straight to win by a head from the outsider Savernake. Third was second favorite Rustic three lenths back. The purse was worth £7,550. (By John Osborne)
