Age: 54
Background:
Aidan O’Brien has a phenomenal list of big race victories to his name. In 2017, he eclipsed American training legend Bobby Frankel’s record for the most Group 1 wins in a season with 28 for the year, three more than Frankel’s mark. A champion amateur jumps jockey in Ireland, he was assistant trainer to Jim Bolger before taking out a trainers’ licence in 1993 – he sealed Ireland’s champion trainer title for the 23rd time in 2020 (22nd consecutively). He enjoyed remarkable success with jumpers before teaming up with John Magnier’s Coolmore operation at the legendary Ballydoyle training base in 1996; a year later, he became Ireland’s youngest ever champion trainer on the flat. O’Brien has trained a host of champions including super sire Galileo, High Chaparral, Giant’s Causeway, Rock Of Gibraltar, Yeats, Cape Blanco, Minding and St Mark’s Basilica, as well as the great hurdler Istabraq. He broke new ground in 2014 with his first winner in Australia, Adelaide, in the W.S. Cox Plate, and in December 2015 Highland Reel gave him his first Hong Kong win. In 2020 Mogul gave him a third win in the Hong Kong Vase, making him the most successful trainer in Vase history. His outstanding performers in 2023 include Auguste Rodin, Paddington, Luxembourg, Savethelastdance and Warm Heart.
