1971: two-year-old season Boucher won two of his three races as a two-year-old in 1971. After winning a maiden race he was moved up in class and won the
Group Two Beresford Stakes at the
Curragh. He was then sent to England to contest the Group One
Observer Gold Cup at Doncaster. He finished fourth behind the English-trained
High Top, who went on to win the following season's
2000 Guineas.
1972: three-year-old season Boucher began his three-year-old season by winning the
Nijinsky Stakes. He was then sent to England for the
Chester Vase, an important trial race for
The Derby. He started favourite, but made no impression, finishing last of the six runners behind Ormindo. He was subsequently found to be suffering from a viral infection and was off the course for three months. by half a length from Our Mirage, with
The Oaks winner Ginevra four lengths further back in third. The race was run on extremely soft ground and the winning time of 3:28.71 was the slowest recorded at Doncaster in the 20th century. On his only subsequent appearance, Boucher ran in the
Prix de l'Arc de Triomphe, a race for which he had reportedly been strongly fancied by Vincent O'Brien. He raced prominently and contested the lead in the straight but was outpaced in the closing stages and finished unplaced behind San San. ==Assessment==
