Arnaud Delacour took out his trainer's license in 2013 and picked up his first stakes win that year at Delaware Park with Margano. He made Breeders' Cup debut in 2014 with Ageless - his first career graded stakes winner - who finished fourth in the Breeders' Cup Turf Sprint.
Arnaud Delacour won the 2015 Coolmore Lexington Stakes with the Jacksons' homebred Divining Rod, who is on target to become Delacour's first starter in a Triple Crown race in the Preakness Stakes where he finished third.
