After her owners paid a supplemental fee to start in the 1985 Breeders’ Cup Turf for $240,000, Pebbles justified her favoritism in a field of 14 by holding off Strawberry Road by a neck at Aqueduct. Pebbles’ victory, the first in the Breeders’ Cup by a horse trained in Great Britain, gave jockey Pat Eddery his initial Breeders’ Cup victory as well as the initial Championships triumph for trainer Clive Brittain. Trailing Pebbles that day were 1984 Turf winner Lashkari and Theatrical, who would win the Breeders’ Cup turf in 1987. Pebbles won the 1985 Eclipse Award as champion turf female.
Prior to her career-ending victory at Aqueduct, Pebbles had won the Dubai Champions Stakes (Group 1) at Newmarket and the Coral Eclipse (Group 1) at Sandown. Pebbles, who died in 2005, was known to consume a pint of Guinness daily in her racing days.
