1998: two-year-old season Dubai Millennium made his debut as a two-year-old at
Yarmouth in October 1998. He started odds-on favourite and won by five lengths despite being eased down by jockey
Frankie Dettori in the closing stages. At the end of the year, Dubai Millennium was transferred to the stable of
Saeed bin Suroor and wintered at the
Godolphin training facility in Dubai. During the winter, he began to appear in the betting list for the following year's Derby, although some felt that his name was the main reason for the attention.
1999: three-year-old season Dubai Millennium began his three-year-old season at
Doncaster in May, where he was "impressive" in leading from the start and winning by nine lengths. On his next start, he was moved up in class and distance for the
Listed Predominate Stakes over a mile and a quarter at
Goodwood, a recognised trial for the
Derby. Accompanied by a large Godolphin entourage and looking "magnificent", Immediately afterwards, his connections expressed no worries about the Derby distance, although some concern was expressed about the possibility of firm ground, which was felt to be unsuitable for such a big, heavily built horse. and was sent to Epsom for the Derby, where he was made favourite, although his starting price of 5/1 reflected the open nature of a race in which many lightly raced, untested colts were entered. He pulled hard early on, and after making a brief effort early in the straight, finished ninth of the sixteen runners, beaten just over nine lengths by
Oath. It was his only defeat and the only time he was tried over the mile and a half distance. Following the Derby, Dubai Millennium was campaigned over shorter races for the rest of the season. In July, he was sent to France for the Group Two
Prix Eugène Adam at Maisons-Laffitte and led from the start to win "unchallenged" by three lengths. Hopes that he would be matched against
Royal Anthem in the
International Stakes were not fulfilled as he was instead brought back to one mile for the
Prix Jacques Le Marois at
Deauville. On heavy, rain-softened ground he once again led all the way and "surged" clear in the closing stages to beat the
Grand Prix de Paris winner Slickly by two and a half lengths. The leading French colt
Sendawar was withdrawn because of the soft ground. After the race, Dettori called Dubai Millennium "a champion". On his final start of the year, in the
Queen Elizabeth II Stakes at
Ascot, he took the lead two furlongs from the finish and pulled clear to win by six lengths. After the race, Sheikh Mohammed made clear his view that Dubai Millennium was the best horse ever prepared by his Godolphin organisation and that he would be aimed at the following year's
Dubai World Cup. In the World Cup three weeks later, he led after a furlong and pulled steadily away from the field in the closing stages to win in "devastating fashion" beating
Behrens by six lengths with the rest of the opposition at least five lengths further back. His performance in winning the world's most valuable horse race in track-record time was acclaimed as an "awesome display", and Dettori called the colt "the best I've ever ridden... absolutely unbelievable". On his return to Europe, Dubai Millennium contested the
Prince of Wales's Stakes at
Royal Ascot, in which he was ridden by
Jerry Bailey, Dettori having been injured in a plane crash. In this race, he was finally matched against Sendawar, who by now had won four Group One races and was unbeaten for more than a year. Such was the reputation of the French colt that, for the only time in his career, Dubai Millennium was not the favourite, starting at odds of 5/4 behind Sendawar at 6/5. The challenge did not materialise, however, with Dubai Millennium leading from the start and finishing eight lengths clear of the German challenger Sumitas, with Sendawar, who had attempted to track the winner throughout the race, fading into fourth. When Bailey was asked to compare Dubai Millennium with the American champion
Cigar, he described him as "equally impressive." Sheikh Mohammed clearly considered Dubai Millennium the greatest racehorse in the world and sought to race him against Michael Tabor's
Arc and
King George winner
Montjeu, offering to pay Montjeu's entry fee to the
Breeders' Cup. Tabor resisted the challenge but told the media he wanted the two horses to be pitted against each other. A media circus erupted, culminating in Sheikh Mohammed proposing a one:one meeting between the two horses and putting down $6 million to back Dubai Millennium to win. Tabor was to match the wager if he took up the challenge. On the morning of Saturday, August 5, as copies of
Racing Post bearing the challenge to Tabor from Sheikh Mohammed were distributed, Dubai Millennium suffered a broken leg (a "lateral condylar fracture") in training. His life was saved by an operation, but his racing career was over. ==Race record==
