Lammtarra's racing career was short, but very sweet. In all he raced just four times. All four outings resulted in victory. He raced just once as a two year old before being sent to the 1995 without the benefit of a prep race. He became the first horse to win the Derby on his seasonal debut since 1995 and beat the Derby record time in the process. The previous record had stood for almost sixty years. In winning the Derby he became the first winner to have had a Derby winning sire (Nijinsky) and an Oaks winning dam (Snow Bride). After the Derby he went on to win both the King George VI and the Prix de l'Arc de Triomphe. He is the only horse other than Mill Reef to have captured all three of these races.
