After finishing second on her only start as a two-year-old, Camarine was undefeated for the next three years, winning thirteen consecutive races at distances ranging from five furlongs to two and a half miles.

The filly was never entered for any of the British Classic Races but proved herself the best of her generation by beating the winners of both The Derby and The Oaks in the space of three days at Newmarket in October 1831.

[4] In early 1831, Camarine entered the ownership of Sir Mark Wood, 2nd Baronet, whose other good horses included Lucetta (Ascot Gold Cup) and Galantine (1000 Guineas).

In a field of eighteen juveniles, many of whom were described as "very good-looking things"[7] she started at odds of 10/1 and finished second, a length behind Lord Cleveland's colt by Emilius (later named Marcus).

[8] The "Juniper filly" had not been entered in any of the British Classic Races, which meant that she had limited opportunities to compete against the best horses of her generation in the early part of 1831.

The filly was scheduled to run a match race against the three-year-old colt Zany at the Newmarket Second Spring meeting in May, but was withdrawn from the contest, with Wood paying a £79 forfeit.

On the opening day she started odds-on favourite for a five furlong Sweepstakes and won from Lord Egremont's filly (later named Miss Petworth).

On the opening day of the meeting she started joint favourite with the Derby winner Spaniel, and defeated the colt by a length in the Trial Stakes over ten furlongs.

[16] Camarine began her four-year-old season in the Claret Stakes over two miles at the Craven meeting in April in which her only rival was Circassian, a Yorkshire-trained filly who had started favourite for the 1831 Oaks.

[18] In June Camarine raced away from Newmarket for the first time when she ran in the Ascot Gold Cup over two and a half miles in front of a large and enthusiastic crowd which included the King.

Rowton, ridden by Sam Chifney, made the running from The Saddler, with Camarine held up in third before Robinson moved her up to challenge for the lead in the straight.

The older horse hung away from the rails and appeared to have hampered the filly in the closing stages; it was only with some difficulty that Wood was persuaded not to lodge a formal objection.

[22] At the Houghton meeting on 1 November Camarine was scheduled to run a match race in which she was set to concede nineteen pounds to John Gully's St Leger winner Margrave over ten furlongs.

The mare won "in a canter"[24] by a length from Rubini, only for the race to be declared void by the judge who decided that a false start had caused two horses to be left behind.
