City of Troy, trained by Aidan O'Brien, faced a disappointing result at the Breeders' Cup Classic, finishing eighth after struggling with the dirt track's kickback. Despite high expectations and comparisons to legendary horses, the transition from turf to dirt proved challenging for the Derby-winning colt. The race was won by Sierra Leone, with City of Troy’s ownership still seeing success through their Coolmore silks. O'Brien's longstanding ambition to win this race remains unfulfilled, highlighting the difficulties European horses face on American dirt tracks. The Breeders' Cup also featured remarkable performances from European horses in turf races, with Charlie Appleby achieving success with Rebel’s Romance and Rossa Ryan delivering a standout ride on Starlust in the Turf Sprint.
