Aidan O'Brien
The master of Ballydoyle — one of the most successful Flat trainers in the history of the sport.
Aidan O'Brien trains the Coolmore horses at Ballydoyle in County Tipperary and has redefined big-race Flat training, winning Classics and Group 1s across Europe and beyond year after year. The operation's strength in the top middle-distance and Classic races is without parallel.
As with the big jumps yards, O'Brien often runs several in a Group 1, using pacemakers and multiple entries tactically — so understanding which is the stable's first string, and how a race is likely to be run, is key to reading his runners. Ballydoyle two-year-old and Classic form sets the European standard.
Known for
- Numerous Epsom & Irish Derby wins
- Record Classic haul
- Global Group 1 success
