What is "boldboy"

Boldboy (1970 – September 1998) was an Irish-bred, British-trained Thoroughbred racehorse. He raced for eight seasons in the 1970s and was one of the most popular and successful racehorses of his era. As a two-year-old he showed ability, but his ungovernable temperament led to his being gelded. In the following year he won the Greenham Stakes, Prix de la Porte Maillot, Diadem Stakes and Challenge Stakes. In 1974 he won the Lockinge Stakes and recorded the first of his four wins in the Abernant Stakes. After failing to win in 1975 he returned to form in 1976 to win the Abernant Stakes and the Sanyo Stakes. He reached his peak in 1977, when he repeated his previous wins in the Abernant Stakes, Sanyo Stakes and Challenge Stakes as well as taking the Vernons Sprint Cup. He won a fourth Abernant Stakes in 1978 and was retired in the following year. Apart from his wins he was placed in many important races but, as a gelding, was unable to compete in European Group One events under the rules which prevailed at the time.
