1985: two-year-old season Before Sonic Lady appeared on the racecourse she had acquired a reputation as the best filly in Stoute's stable and had been supported in the betting for the
1000 Guineas. She made her debut in the Blue Seal Stakes over six
furlongs at
Ascot Racecourse in September. Sonic Lady accelerated clear of her eight opponents in the final quarter mile and won by seven
lengths from Warm Welcome despite drifting to the right in the closing stages. Despite never having contested a
Group race she ended the year as the 3/1 favourite for the 1000 Guineas. She was traveling easily throughout the race and pulled clear of the field in the closing stages to win by three lengths from Lady Sophie, with the
Cheveley Park Stakes winner Embla in fourth place. Her reappearance was the front-page story on the first edition of the newly founded
Racing Post: the rival
Sporting Life's front page had featured Embla. On 1 May Sonic Lady started the
6/4 favourite for the 173rd running of the 1000 Guineas over the Rowley Mile course at Newmarket. Swinburn opted to ride Sonic Lady in preference to her stable companion Maysoon who had won the
Fred Darling Stakes at
Newbury. She became unsettled in the preliminaries and arrived at the start in an agitated state. She took the lead approaching the final quarter mile but was overtaken in the closing stages and finished third, beaten three quarters of a length and a head by
Midway Lady and Maysoon. For Sonic Lady's next race, the Irish 1000 Guineas at the
Curragh on 24 May she was equipped with a new bridle incorporating a rubber noseband, which was designed to help her settle. Her participation in the race was in doubt as she arrived without her equine passport but she was allowed to run after a copy was
faxed from Newmarket. She started 4/1 joint favourite with the
Poule d'Essai des Pouliches winner Baiser Vole and won easily by two lengths.
Summer At
Royal Ascot in June Sonic Lady started the 8/15 favourite for the
Coronation Stakes (then a Group Two race) and won impressively Three weeks later she was matched against the leading three-year-old filly
Forest Flower in the Child Stakes at Newmarket. The early pace was very slow and Swinburn opted to send the filly into the lead after two furlongs. In the closing stages she held off the sustained challenge of the
Aga Khan's filly Shaikiya to win by a head with Forest Flower ten and a half lengths back in fourth. Sonic Lady did not race again until 26 September, when she finished third behind
Milligram and
Miesque in the
Queen Elizabeth II Stakes at Ascot. In November, the filly was sent to California for her second attempt at the Breeders Cup Mile, with the
Panamanian jockey
Laffit Pincay replacing Swinburn. Racing on medication, including
Lasix and
Bute, she started the 2.9/1 favourite, but had no answer to the finishing speed of Miesque and finished third of the fourteen runners. ==Assessment==
