1817: three-year-old season Ebor did not race as a two-year-old, beginning his racing career at
York Racecourse on 22 May 1817. He started at odds of 3/1 and finished third of the six runner's behind Christopher Wilson's colt Parlington and Richard Gascoigne's unnamed brown colt. Ebor did not race again until 22 September, when he was one of eighteen colts and fillies to contest the forty-second running of the St Leger Stakes at
Doncaster Racecourse. The strong favourite for the race was Richard Watt's unnamed Whitelock colt (later named
Blacklock) who started at odds of 4/5, despite having his first run of the season. Ebor, ridden by Robert Johnson, was a 20/1 outsider. The Whitelock colt, ridden with great confidence by John Jackson, took the lead in the straight and seemed poised to win very easily. In the closing stages, Jackson, who had boasted that he would win the race in a
canter, began to ease the favourite down, apparently unaware that Bob Johnson was delivering a strong challenge on Ebor along the rail. By the time Jackson was alerted to the danger by the shouts of the crowd it was too late, and Ebor repelled the favourite's renewed challenge to win by a
neck, with Restless in third place. Although there was a great deal of ill-feeling directed at Jackson, it was generally acknowledged that the favourite's defeat was a result of overconfidence rather than dishonesty.
1818: four-year-old season As a four-year-old, Ebor was unbeaten in three races, although he was not tested at the highest level. He did not appear until the York August meeting where he had two engagements, the first in a four-mile Produce Sweepstakes for four-year-old colts and fillies. The betting suggested that he was his owner's second string, as the favourite was Henry Peirse's grey filly by Orville out of Ebor's half-sister Lisette. The filly's chance ended when she fell at the start, and Ebor won the race from Donna Rodriguez, the only other runner. Three days later, Ebor started at odds of 1/3 for a two-mile Sweepstakes at the same course, and won from
Lord Fitzwilliam's colt Anselmo. Ebor returned to Doncaster in September for his only other appearance of the season. His owner was able to claim the prize in a four-mile sweepstakes without having to race his colt, as the other four entries were withdrawn, allowing Ebor to
walk over.
1819: five-year-old season Before being retired to stud, Ebor made one appearance as a five-year-old in 1819. He ran for the third consecutive year at Doncaster's St Leger meeting in September, contesting the
weight-for-age Fitzwilliam Stakes over one and a half miles. He finished second of the eight runners behind Mr Fox's four-year-old Merlin, the 1/2 favourite. ==Stud career==
