2018: two-year-old season Royal Marine made his debut in a minor race over six
furlongs at
Newmarket Racecourse on 25 August in which he was ridden by Pat Cosgrave and started the
9/4 second favourite in an eleven-runner field. He was "unruly" in the
starting stalls and failed to live up to expectations in the race as he came home sixth behind Jash, more than twelve
lengths behind the winner.
Oisin Murphy took the ride when the colt started at odds of 11/2 for a seven furlong
maiden race at
Doncaster Racecourse on 14 September. Royal Marine led from the start and recorded his first success as he came home two and a quarter lengths clear of the
John Gosden-trained Turgenev. On 7 October Royal Marine was sent to France and moved up sharply in class to contest the
Group 1 Prix Jean-Luc Lagardère over 1600 metres at
Longchamp Racecourse. Ridden by Murphy he started the 5/1 third choice in the betting behind Anodor (
Prix des Chênes) and Boitron (
Denford Stakes), while the other three runners were Broome (runner-up in the
Juvenile Stakes), Shaman and Dark Jedi. After racing in second place behind Broome, Royal Marine took the lead in the straight and stayed on well to win by a neck with Anodor three quarters of a length back in third place. After the race Saeed bin Suroor said "Royal Marine has been good since he won at Doncaster last time. What I like about him is he stays well, but he also has plenty of speed. He's a big, strong horse and in the future he could be anything. He's still a baby and he will be better in the future. We'll talk to Sheikh Mohammed and make a decision about what we are going to do".
2019: three-year-old season In the winter of 2018/19 Royal Marine was sent to Godolphin's base in the United Arab Emirates and made his three-year-old debut when finishing fourth in the UAE 2000 Guineas Trial at
Meydan Racecourse on 10 January. On his return to Europe the colt started the 13/8 favourite for the
Craven Stakes (a major trial for the
2000 Guineas) over the Rowley Mile at Newmarket. Ridden as on his previous start by
Christophe Soumillon he pulled hard in the early stages before coming home fourth of the eight runners behind Skardu. In the 2000 Guineas at Newmarket on 4 May he never looked likely to take a hand in the finish and came home tenth behind
Magna Grecia, beaten more than sixteen lengths by the winner. At
Royal Ascot in June he started a 33/1 outsider for the
St James's Palace Stakes and finished unplaced behind
Circus Maximus. In July he finished last of the twelve runners behind
Too Darn Hot in the
Prix Jean Prat at
Deauville Racecourse. A month later he was
gelded.
2020: four-year-old season In 2020 Royal Marine returned to the track to compete in
handicap raced but failed to win in five starts. After finishing unplaced in two races at Meydan early in the year he returned to Europe and finished fourth over seven furlongs at Newmarket in August. Later that month he ran fifth on the
Polytrack surface at
Chelmsford City Racecourse. On his final run of the season he was moved up in distance and produced a better effort over ten furlongs at
Newbury Racecourse in September, finishing second by a neck to the three-year-old Ilaraab after encountering trouble in running. ==Pedigree==
