[2] Crimplene's dam, Crimson Conquest, who won one minor race as a two-year-old, was descended from Bayrose, ancestor of the Poule d'Essai des Poulains winners Blue Tom and Fast Topaze.

Starting a 40/1 outsider, she pulled hard in the early stages before weakening to finish seventh of the nine runners behind the locally trained Jemima.

[7] At the end of the season, representatives of Sheikh Mohammed's Godolphin organisation purchased Brittain's Teggiano, the winner of the Fillies' Mile, but showed no interest in Crimplene.

[8] In March, Crimplene was sent to the United Arab Emirates and was matched against colts in the UAE Derby on dirt at Nad Al Sheba Racecourse.

On her return to Europe she ran in the Fred Darling Stakes at Newbury Racecourse and finished third to Iftiraas, with the future 1000 Guineas winner Lahan in fourth place.

[9] She was then sent to Italy for the Premio Regina Elena in Rome where she finished third to the locally trained fillies Xua and Timi, after being roughly treated by the Italian stalls handlers.

[10] Iftiraas, Seazun, Amethyst and the Poule d'Essai des Pouliches winner Blumamba were among Crimplene's rivals when she contested the Group One Coronation Stakes at Royal Ascot on 23 June.

[8] In August, Crimplene was moved up in distance and matched against older fillies and mares in the ten furlong Nassau Stakes at Goodwood Racecourse.

[15] Commenting on the filly's fourth consecutive major victory, Brittain said: "There may have been a doubt about whether we were right to go a mile and a quarter, but as I said before the race, when you've got an animal of class they can go any distance".

Crimplene's final racecourse appearance came on 4 November, when she was sent to the United States for the Breeders' Cup Distaff over nine furlongs on dirt at Churchill Downs.
