Aidan O'Brien's horse City Of Troy is set to compete in the Breeders' Cup Classic following an impressive victory in the G1 Juddmonte International, where he broke the 10-furlong track record. Despite a previous setback in the 2000 Guineas, he has emerged as a dominant force, also winning the Derby and Coral-Eclipse this season. O'Brien plans to prepare City Of Troy for the different dirt surface at Del Mar with a gallop at either Southwell or Wolverhampton before the race. Coolmore partner Michael Tabor expressed concerns over the challenge of adapting to the new surface but remains hopeful for a successful outcome. City Of Troy's recent performances have earned him a rating of 130p, making him the highest-rated horse in training. O'Brien's stable continues to thrive, with other contenders poised for upcoming events, including the St Leger and juvenile Group Ones.
