He later became a very successful breeding stallion whose other offspring included Easy Goer, Alysheba, Turkoman, Strike the Gold, Criminal Type and Miss Oceana.
He took the lead before half-way and accelerated away in the last quarter mile to win "very easily" by seven lengths from Dolpour, a colt who later that year was beaten only a head when finishing second in the Champion Stakes.
[5] The colt was then stepped up in class and distance for the Group 3 Lingfield Derby Trial over one and a half miles on 13 May and started second choice in the betting behind the undefeated Pirate Army.
Less than two weeks after his defeat at Epsom, Cacoethes started odds-on favourite for the Group 2 King Edward VII Stakes at Royal Ascot in which he was partnered by Pat Eddery.
He was restrained by Eddery in the early stages before going to the front approaching the final furlong and won by three quarters of a length from Zayyani (winner of the Greenham Stakes).
His season began disappointingly as he finished fourth behind Relief Pitcher when favourite for the Listed Festival Stakes over ten furlongs at Goodwood Racecourse in May.
In July he made his second attempt to win the King George VI and Queen Elizabeth Diamond Stakes and started the 11/2 third choice in the betting behind In The Wings and Old Vic.
[8] After a break of over two months Cacoethes returned in the Group 3 Cumberland Lodge Stakes at Ascot in September in which he ran second to Ile de Nisky, beaten half a length when conceding five pounds to the winner.
In October Cacoethes was sent to the United States to contest the Grade 1 Turf Classic over one and a half miles at Belmont Park and started 5/2 second favourite behind the Canadian champion With Approval in a six-runner field which also included El Senor (Sword Dancer Stakes), Shy Tom (third in the Travers Stakes), Alwuhush (Premio Presidente della Repubblica) and Fast 'n' Gold (Rutgers Handicap).
