1978: three-year-old season Inkerman began his racing career in a
maiden race over ten furlongs at the
Curragh on 13 May and won by four
lengths from his stablemate Noble Quillo. Two weeks later he was stepped up in class for the Gallinule Stakes over one and a half miles and won again, coming home six lengths clear of Encyclopedia. The colt quickly became regarded as a major contender for
The Derby ten days later especially after
Lester Piggott opted to ride the colt. Piggott was looking to follow up his victories on
Empery 1976 and
The Minstrel in 1977 and win the race for a record ninth time. Despite his lack of experience Inkerman started favourite but after racing close to the lead in the early stages he dropped away quickly in the straight and finished twenty-first of the twenty-five runners behind
Shirley Heights. It was reported that the colt had "swallowed his tongue".
1980: five-year-old season In 1980 Inkerman continued to race exclusively in California. He was beaten in allowance races on his first two starts and then ran second to Bold Tropic in the American Handicap. On 21 July on his final racecourse appearance, he made his second attempt to win the Sunset Handicap. Ridden by
Willie Shoemaker, he won the race, beating his front-running stablemate Obraztsovy into second place. ==Stud record==
