At four she raced creditably against male opposition before returning to all-female competition to win a second Yorkshire Oaks and the Breeders' Cup Filly & Mare Turf.
She went on to become an outstanding broodmare, producing Greek Dance (Bayerisches Zuchtrennen), Mountain High (Grand Prix de Saint-Cloud) and New Morning (Brigadier Gerard Stakes).

Racing on soft ground she tracked the favourite Kazzia, but after briefly moving up to challenge the leader early in the straight she faded in the closing stages to finish eighth.
Fallon tracked the leaders on Islington before overtaking Kazzia two furlongs from the finish and drawing clear to win by five lengths from the Oaks d'Italia winner Guadelupe.
On her final appearance as a three-year-old, Islington was sent to the United States for the Breeders' Cup Filly & Mare Turf at Arlington Park, Chicago.
In a rough and controversial race, she finished third, beaten a neck and a head by High Chaparral and Falbrav, with the favourite Alamshar in fourth place.
The favourite raced in fourth as Bien Nicole opened up a ten length lead before coming back to the field approaching the straight.
"[9] On her final appearance, Islington contested the Japan Cup at Tokyo Racecourse but made little impression, finishing ninth of the eighteen runners behind Tap Dance City.
