Sea The Stars, who became one of the greatest racehorses of all time when landing a sixth successive Group 1 in the Prix de l'Arc de Triomphe this month, has been retired.

Trainer John Oxx had said after the colt's Longchamp victory that a crack at next month's Breeders' Cup Classic was unlikely and retirement for the 2,000 Guineas and Epsom Derby winner was confirmed today.

“It has been decided after discussions with owner Christopher Tsui that Sea The Stars will not take part in the Breeders' Cup at Santa Anita on 7 November,” said Oxx.

“He is now retiring from racing, but I have no information on stud career details and an announcement will be made at a much later date when plans have been finalised.”

“Sea The Stars has been in regular fast work from 3 March, with his final workout on
2 October. He's been in intensive training for seven months with only a three-week break after the Eclipse Stakes at the beginning of July.

“We feel it is unfair to keep him going any further given his unprecedented record of achievement in the last six months.”

The three-year-old lost just one of his nine races during his two years on the track — in which he amassed nearly £4.5million in prize money — and that was his racecourse debut at the Curragh in July 2008 when he finished fourth.
