Ditto was a bay horse, described as having "great size" and a "fine temper"[1] bred by his owner Sir Hedworth Williamson.
On 17 April he ran in the Claret Stakes over the two mile "Ditch In" course in which he was re-opposed by Frank Standish's still unnamed Brother to Stamford.
Ditto started the 4/7 favourite and reproduced his Derby-winning form to beat the Brother to Stamford and Discussor to take the first prize of 1,200 guineas.
Ditto returned for the Craven Stakes, an all-aged race run over ten furlongs "Across the Flat" at Newmarket on 15 April 1805.
[7] Three days later he ran a match race against Lord Foley's Sir Harry Dimsdale, a grey horse who had finished unplaced in the Craven Stakes.
Running over Newmarket's four mile Beacon Course, Ditto started favourite but suffered his first defeat as he failed to concede seven pounds to his opponent.
He carried top weight of 131 pounds and started 7/4 favourite but finished unplaced behind Hippomenes[10] Later the same afternoon, Mr Wilson claimed a 20 guinea forfeit when Ditto's scheduled opponent, Hedley, was withdrawn from a one-mile match race.
[5][13] Ditto's most notable offspring was Luzborough, who won twenty-five races and was exported to the United States where he became a very successful sire.
