The Tetrarch
There is (as with many star two-year-olds) the question of what The Tetrarch's – and his competition's – continued physical development would have meant to his racing performance at age three. In 1913 The Tetrarch easily beat all comers including Stornoway, who won several races that year; among them were the Gimcrack and Norfolk Stakes (now The Flying Childers Stakes). However (as noted in the Thoroughbred Heritage website), none of The Tetrarch's races were more than six furlongs (¾ mile) and because he never raced at age three, he was not tested at standard mile to mile-and-a-half distances. His bloodlines, though, pointed to stamina.
