He got his first trainer's licence in 1986. In 1994 he trained Las Meninas to win the 1000 Guineas. His other major winners include Tarascon (Irish 1000 Guineas) and Kostroma (Beverly D. Stakes). Stack survived a life-threatening viral infection in December 1998. Following his recovery, he had further international success with Myboycharlie (Prix Morny) and Alexander Tango (Garden City Stakes). He trained at Golden, County Tipperary and retired as a trainer at the end of the 2016 flat racing season, handing over the licence to his son, James "Fozzy" Stack.
