Unfuwain (5 March 1985 – 16 January 2002) was an American-bred, British-trained Thoroughbred racehorse bred and owned by Hamdan Al Maktoum. In a career of ten starts, lasting from 1987 to 1989, he won four Group races and was placed in the King George VI and Queen Elizabeth Stakes and the Prix de l'Arc de Triomphe. He went on to become a successful sire. Background Unfuwain was a strongly-built, 16.1 hand bay horse, bred in Kentucky by his owner Hamdan Al Maktoum. He was one of the last important winners sired by Northern Dancer. As a son of the mare Height of Fashion, he was a half-brother to several important winners including the Derby winner Nashwan and the multiple Group One winner Nayef. He went into training with Dick Hern at West Ilsley and was ridden in all but one of his starts by the stable jockey Willie Carson. Racing career 1987: two-year-old season Unfuwain made two starts in the late summer of 1987. On his debut, he finished second in a 27-runner maiden race at Newbury to the subsequent St Leger winner Minster Son. He confirmed the promise of this run with a win in the Haynes, Hanson and Clark Conditions Stakes at the same track a month later. His early runs established his racing style; he lacked acceleration but was able to sustain a "relentless" gallop over sustained distances. 1988: three-year-old season In April 1988 Unfuwain began his three-year-old career by winning the Warren Stakes at Epsom by 15 lengths. Two weeks later he move up in class and recorded an eight length win in the Group Three Chester Vase, taking the lead in the straight and finishing "unchallenged". As a result of these victories he was a leading fancy for the 1988 Epsom Derby, starting as the 9-2 second favourite. He disappointed in the classic, finishing seventh behind Kahyasi. This was the only occasion, apart from his debut, on which he was beaten by horse of his own generation. It was also the only race of his career in which he was not ridden by Carson, who chose to ride Minster Son, a colt he had bred himself. The ride instead went to Steve Cauthen. After a brief break he returned in the Princess of Wales's Stakes and, facing older horses, produced his best performance, taking the lead two furlongs out and pulling away to win by
