Blenheim was slow to find his form as a three-year-old and began his 1930 campaign by running unplaced behind Christopher Robin in the Greenham Stakes at Newbury. Despite his poor performance in the trial, he was well-fancied for the 2000 Guineas at Newmarket two weeks later. He finished fourth of the twenty-eight runners behind Diolite, Paradine and Silver Flare.
