1992: two-year-old season Shadayid began her racing career in a six
furlong maiden race at
Ascot Racecourse in June. She started
13/8 favourite and won by six
lengths. After a break of three months, Shadayid returned to Ascot for the Kensington Palace Stakes over seven furlongs. She started odds-on favourite and recorded a three and a half length win without being asked for a serious effort ("hard held"). Nine days after her second Ascot win, Shadayid was stepped up in class for the Group One Prix Marcel Boussac at Longchamp. 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.
1993: three-year-old season On her first appearance as a three-year-old, Shadayid was sent to
Newbury for the Fred Darling Stakes, a trial race for the 1000 Guineas. Her opponents included the
Lowther Stakes winner Only Yours and the
Cherry Hinton Stakes winner Chicarica. Shadayid started 8/11 favourite and won comfortably by three lengths. Two weeks later, Shadayid started 4/6 favourite for the 1000 Guineas over Newmarket's Rowley Mile course. Her closest rival in the betting was the
Luca Cumani-trained Crystal Gazing, a filly who had won the
Rockfel Stakes and the
Nell Gwyn Stakes. Carson restrained the filly in the early stages before moving forward in the second half of the race. 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. A month after her Newmarket victory, Shadayid was moved up in distance to contest her second Classic, the
Oaks, over one and a half miles at
Epsom Downs Racecourse. The race produced an upset result, with Jet Ski Lady, a 50/1 outsider, leading for most of the race and winning by ten lengths, with Shadayid tiring in the closing stages to lose her unbeaten record as she finished third. 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. Shadayid was in third place entering the straight and appeared to have every chance but was beaten three quarters of a length into second by Kooyonga. In July, Shadayid ran against
colts and older horses in the Sussex Stakes at
Goodwood Racecourse. She started 9/4 favourite and finished second of the eight runners behind Second Set. In September, the filly was brought back in distance for the Sprint Cup over six furlongs at
Haydock Park. Racing against specialist sprinters she finished third behind
Polar Falcon and
Sheikh Albadou. On her final European start, Shadayid led until the final furlong before finishing third to
Selkirk and Kooyonga in the Queen Elizabeth II Stakes at Ascot, with Second Set fourth and
Hector Protector in sixth. Shadayid's final appearance came in November when she was sent to the United States to contest the
Breeders' Cup Mile at
Churchill Downs. She started a 22/1 outsider and finished seventh of the fourteen runners behind
