Balmerino was the champion three-year-old of his year, winning both the
New Zealand 2000 Guineas and
New Zealand Derby. Those wins and his subsequent success against older horses in both the
Air New Zealand Stakes and in races in Australia confirmed that he would be a landslide winner of the Horse of the Year award in New Zealand. He also won the Australian Three Year-Old of the Year award for the 1975-76 season. Later in his career he travelled to the
Northern Hemisphere and performed very well in some of the best races in
Europe. He won the Group one (G1)
Gran Premio del Jockey Club e Coppa d'Ora in
Italy, before being relegated to second place, and also ran second in the
Coronation Cup and the
Eclipse Stakes. One of Balmerino's most notable performances was in the
Prix de l'Arc de Triomphe of 1978, when he came second in a star-studded field to champion racehorse
Alleged (Timeform rating 138). During 1977 Balmerino had 39 starts in New Zealand, Australia, the United States, England, Italy and France for 21 wins, 9 seconds, 1 third and stakes winnings for the equivalent of (AUD)$400,000. He was joint Champion Older Horse in both England and France for the 1977 seasons and was awarded a
Timeform rating of 133 in 1977 and 124 in 1978. ==Stud career==
