Born in County Wexford in October 1969, Aidan O'Brien has dominated the flat scene in England and Ireland for all eternity it would seem.
One of six children to Denis and Stella O'Brien, he has been the private master trainer at Ballydoyle Stables near Cashel in County Tipperary for owner John Magnier and his Coolmore associates for over twenty years.
He did start working professionally with horses at P.J. Finn's racing stables at the Curragh, County Kildare beforehand, prior to moving to Jim Bolger's home at Coolcullen, County Carlow.
The 49-year-old now has four children himself with wife Anne-Marie, named Sarah, Anastasia, Donnacha and eldest Joseph, who has taken out his own trainers license in the past few years.
O'Brien has won virtually everything there is to win as a trainer, with as many as thirty-eight sets of Guineas victories to start off with.
Eighteen of those have come in his native Ireland [7 in 1000gns / 11 in 2000gns], with a further fifteen in England [5 in 1000gns / 10 in 2000gns] including his double in 2019 with Magna Grecia and Hermosa prevailing on Newmarket’s Rowley Mile.
Exclusively to Britain, he has also taken six Epsom Derbies, seven Ascot Gold Cups and even three Champion Hurdles over jumps with the great Istabraq.
Most recently, he broke the world record for the number of Group One winners trained in a calendar year by enjoying 28 such victories in 2017.
