1905: two-year-old season Gorgos made little impact on his racecourse debut in June 1905 when he finished unplaced in the Triennial Stakes at
Royal Ascot. In the following month, ridden by
Herbert Jones he won July Stakes over five and a half
furlongs at
Newmarket Racecourse at odds of
7/4 from the favoured Alcanzor. A month later he led from start to finish to win the Prince of Wales's Stakes at
Goodwood Racecourse. On his final start of the year he finished third in the Boscawen Stakes at Newmarket in autumn.
1906: three-year-old season On 2 May Gorgos, with Herbert Jones in the saddle, started a 20/1 outsider in field of twelve for the 98th running of the 2000 Guineas over the
Rowley Mile course for which the leading contenders appeared to be Gingal (runner-up in the
Dewhurst Stakes) Bill of Play, Admiral Crichton, Beppo and Frustrator. The
Coventry Stakes winner Black Arrow delayed the start with his "obstreperous" behaviour but then started quickly and led the field to halfway with Gorgos settled behind the leaders. Approaching the last quarter mile Ramrod and Admiable Crichton disputed the lead but the pair then swerved towards the centre of the track allowing Gorgos and the unnamed "Dame Agneta colt" (later named
Sancy) to join the issue. In a closely contested finish Gorgos prevailed by a head from the Dame Agneta colt, with Ramrod a neck away in third. Two weeks later the colt was moved up in distance for the
Newmarket Stakes over ten furlongs and finished third behind Lally and Malua. In the Derby over miles at
Epsom Racecourse on 30 May Gorgos started the 10/1 fifth favourite but was never in serious contention and finished seventh behind
Spearmint. At Goodwood on 2 August Gorgos was stepped up in distance and matched against older horses to contest the
Goodwood Cup over miles and finished third behind Plum Tree. On 12 September the colt ran in the
St Leger over furlongs at
Doncaster Racecourse but after being left behind in a "shockingly bad" start he finished unplaced behind
Troutbeck. Gorgos was "badly knocked about" in the race and never ran competitively again. ==Assessment and honours==
