1994 Tabor paid more than $400,000 for the promising two-year-old thoroughbred Thunder Gulch. The horse went on to win the Kentucky Derby, the Belmont Stakes and the Travers Stakes, narrowly missing the American Triple Crown when he was beaten by less than a length in the Preakness Stakes. Tabor had been looking for a horse to race in America having moved to Miami, Florida, and had been pointed for advice to John Magnier by a mutual friend, J.P. McManus. Demi O'Byrne, the bloodstock adviser to Magnier, advised Tabor on his purchase and Magnier bought half of Thunder Gulch to stand at stud at Coolmore's Kentucky annexe at Ashford. Tabor joined the Coolmore partnership. His money allowed Magnier to become once again a major buyer in the top yearling sales, a role he had not played since the mid-1980s when he had acted in conjunction with Robert Sangster and other associates. In 1995 they bought three of the top four yearlings at the Keeneland Sales and paid 600,000 guineas for the leading lot at Tattersalls' Houghton Sale. That colt, Entrepreneur, went on to win the 2,000 Guineas at Newmarket. Tabor became the owner and co-owner of an extraordinary catalogue of some of the world's best racehorses, generally owning the Coolmore horses in a three-way partnership with Magnier and his wife Sue, and with another former London bookmaker, Derrick Smith, who became involved in the mid-2000s. His Desert King won the Irish 2,000 Guineas and the Irish Derby in 1997, while Entrepreneur took the 2,000 Guineas at Newmarket that same year to give Tabor his first victory in an English Classic. Montjeu won the Irish Derby and the Prix de l'Arc de Triomphe in 1999, while Tabor won The Derby in 2001 and 2002 with Galileo and then High Chaparral, the latter horse also winning the Irish Derby and the Breeders' Cup Turf. Tabor won the Derby again, with Pour Moi in 2011 and with Camelot in 2012, the year that horse also took the 2,000 Guineas and the Irish Derby at the Curragh, though he missed out on the English Triple Crown by finishing second in the St Leger. Tabor was also the breeder, as well as the owner, of Giant's Causeway, winner of numerous Group One races, and in 1995 his Hurricane Run was voted the world's top-ranked racehorse by the International Federation of Horseracing Authorities.
