As a three-year-old he finished third in the 2000 Guineas and was unplaced in The Derby before winning the Sussex Stakes at Goodwood and the St Leger at Doncaster in September. In 1915 he won the City and Suburban Handicap and the June Stakes, a wartime substitute for the Coronation Cup. He became increasingly difficult to train and at the end of the season he was retired to stud where he became a successful sire of broodmares.
WDurbar was a French racehorse. Although not the best of his generation in France he proved too good for the leading British colts in the 1914 Epsom Derby, which he won by three lengths.

In the following spring he won the Craven Stakes and the 2000 Guineas but lost his chance in the Epsom Derby when he became highly agitated before the start. He went on to finish third in the Eclipse Stakes and second in the St Leger before winning the Newmarket St Leger on his final appearance. He died at the age of five in 1916 after a single season at stud.
