started at odds of 6/1 for the Oaks, with the French-trained Alexandrie starting favourite. Carson restrained the filly in the early stages before allowing her to make up ground on the outside and sending her into the lead half a mile from the finish. In the straight she increased her lead with every stride to record a "highly impressive victory" by twelve lengths from Acclimatise, with Royal Heroine (Breeders' Cup Mile) and Cormorant Wood (Champion Stakes) among the beaten fillies. The winning margin was the largest ever recorded in the Oaks and the biggest in any British Classic race since Never Say Die won the St Leger by twelve lengths in 1954. Observers including Timeform speculated that Sun Princess might well have won that year's Epsom Derby if she had contested that race. She was the also the first maiden to win a Classic since Asmena won the Oaks in 1950. Sun Princess bypassed a meeting with the leading Irish filly Give Thanks in the Irish Oaks, being instead sent to Ascot to run against colts and older horses in Britain's most prestigious all-aged race, the King George VI and Queen Elizabeth Stakes. She started 9/4 joint-favourite with the Prix du Jockey Club winner Caerleon, ahead of rivals including Time Charter, Lemhi Gold, Lancastrian (Prix Ganay), Diamond Shoal (Grand Prix de Saint-Cloud) and Awaasif (Yorkshire Oaks). Sun Princess pulled very hard in the early stages as Carson struggled to restrain her. She made steady progress in the straight, but failed to reach the lead and finished third to Time Charter and Diamond Shoal, beaten just under two lengths. A month after her defeat at Ascot, Sun Princess started 6/5 favourite the Yorkshire Oaks, in she was matched against Give Thanks. The Irish filly had won seven of her eight races in 1983, including the Irish Oaks, and was well-supported at 7/4. On this occasion, Sun Princess was allowed to lead from the start and was never in danger of defeat, accelerating clear of her opponents in the straight and running on with "tremendous zest" to win by four lengths from Green Lucia, with Give Thanks a further three lengths back in third. Following her win at York, Sun Princess again faced mixed-sex competition in the St Leger Stakes at Doncaster on 10 September for which started 11/8 favourite. Her main rivals included the Epsom Derby runner-up Carlingford Castle and the
