It was not only her owner Lord Derby whose life was changed by Ouija Board winning the 2004 Oaks. Her victory in the Epsom Classic delivered a new superstar to British racing, and before long she was captivating race-goers all over the world. She won big races on three continents and competed in seven different countries; she won two Breeders' Cup races in the USA; and her showdown with Alexander Goldrun at Goodwood in August 2006 has been hailed as one of the greatest races ever. When she won the Oaks, Ouija Board was the only horse Lord Derby had in training. But it was his ancestor the twelfth Earl of Derby who founded, in the late 18th century, the most famous race in the world, and the extraordinary story of Ouija Board and her exploits is inextricably entwined with the long history of the greatest racing family of all.
