Shadayid was one of the leading two-year-old fillies in Europe in 1990, winning all three of her races including the Group One Prix Marcel Boussac at the Longchamp.
Shadayid was retired from racing to become a broodmare at the end of her three-year-old season after finishing seventh in the Breeders' Cup Mile.
As a granddaughter of the broodmare Balidaress, Shadayid was closely related to many successful Thoroughbreds including the 1000 Guineas winner Russian Rhythm and Cape Cross, the sire of Sea the Stars.
Carson sent the grey filly into the lead in the straight and she quickly went clear of her opponents to win by two lengths from the future Prix de Diane winner Caerlina.
The unplaced horses included Magic Night and Jet Ski Lady who went on to win the Prix Vermeille and The Oaks respectively.
Shadayid took the lead inside the final furlong and went clear to win by two lengths from the Irish-trained Kooyonga, with Crystal Gazing third.

[8] Eleven days after the Oaks, Shadayid returned to a mile for the Coronation Stakes] at Royal Ascot where she was matched against Kooyonga, who had won the Irish 1,000 Guineas since her defeat at Newmarket, and the Poule d'Essai des Pouliches winner Danseuse du Soir.
