Aida (1898 - 1915) was a British Thoroughbred racehorse and broodmare. As a juvenile she finished second on her debut and then defeated the future Epsom Derby winner Volodyovski in the Imperial Produce Stakes. She won the 1000 Guineas on her first appearance of 1901 and then finished a close third in a very strong edition of the Newmarket Stakes. She finished unplaced in the Eclipse Stakes and the St Leger and was retired from racing at the end of the year. As a broodmare she had an enduring influence on the breed through her daughter Herself.
Aida was a bay mare bred by Henry Chaplin's Blankney Stud. During her racing career she was owned by Sir James Miller and trained by George Blackwell at Newmarket, Suffolk.[2]
Aida’s sire Galopin was an outstanding racehorse who won the Derby in 1872 and went on to be a successful and influential stallion, siring St Simon and Donovan and being Champion sire on three occasions. Her dam, Queen Adelaide, was an outstanding racemare who won the July Stakes and Dewhurst Stakes and was placed in the Epsom Derby, Epsom Oaks, 1000 Guineas and Middle Park Stakes. She was a daughter of Adelaide, the foundation mare of Thoroughbred family 9-h.[3]
Until 1913, there was no requirement for British racehorses to have official names and two-year-olds were allowed to run without names until 1946.[4] The filly who became Aida began her racing career unnamed and was generally referred to as the Queen Adelaide filly.
The Queen Adelaide filly made her racecourse debut in the Champion Breeders' Biennial Foal Stakes at Derby Racecourse in which she finished second to Sagitta.[5] On 7 October the still unnamed filly contested the £3,000 Imperial Produce Stakes over six furlongs at Kempton Park Racecourse and won from the colt Volodyovski.[6]
On 4 May Aida was one of fifteen fillies to contest the 88th running of the 1000 Guineas and started the 13/8 favourite ahead of Princess Melton and St Aldegonde. Ridden by the American jockey Danny Maher she took the lead soon after the start and made most of the running, setting a pace which had most of the others struggling entering the last quarter mile. After fighting off a challenge from Santa Brigida, Aida was overtaken by Fleur d'Eté but rallied to wear down her rival in the final strides.[7] She won by a neck from Fleur d'Eté with two lengths back to Santa Brigida in third. The fact that she was running for the first time as a named horse led to some confusion in telegraph reports of the race with "Aida" being assumed to be a misreading for "Art"[8] or "Arta".[9]
On her next appearance twelve days later the filly was moved up in distance and matched against male opposition in the Newmarket Stakes over ten furlongs. She produced arguably her best performance as he finished a very close third behind William the Third and Doricles in what was described as "one of the finest struggles ever seen".[10] Aida bypassed the Epsom Oaks and reappeared in the Eclipse Stakes over ten furlongs at Sandown Park on 19 July. She started a 20/1 outsider and finished unplaced behind Epsom Lad.[11] In September Aida contested the St Leger over furlongs at Doncaster Racecourse and came home tenth of the thirteen runners in a race won by Doricles.[12]
In their book, A Century of Champions, based on the Timeform rating system, John Randall and Tony Morris rated Aida an "inferior" winner of the 1000 Guineas.[13]
Aida was retired from racing to become a broodmare. She produced at least five foals between 1903 and 1915:
Aida died in October 1915 at the Sledmere Stud.[14] [15]
