1830: three-year-old season Charlotte West began her racing career on 15 April 1830 at the Newmarket Craven meeting. Ridden by
James "Jem" Robinson she ran a match race against a colt named Coventry over the Ditch Mile. The colt was favoured in the betting, but the filly won to win a prize of £200. Two weeks later, Lord Jersey's filly was one of seven fillies to contest the 1000 Guineas Stakes over the same course and distance and started at odds of
5/1 behind the 3/1 joint-favourites Brambilla and Zillah. Partnered again by Robinson, Charlotte West won the classic by a length from Zillah, with Brambilla in third place. According to the Sporting Calendar she won "rather decidedly" after a "business-like" race. A month after her win at Newmarket, Charlotte West was moved up in distance for the Oaks Stakes over one and a half miles at
Epsom. In a field of eighteen runners, she was made 3/1 favourite but finished unplaced behind Mr Scott Stonehewer's filly Variation, a 28/1 outsider. Charlotte West returned to the one mile distance at
Ascot in June for the Royal Stakes. She started at odds of 1/4 and won by two lengths from her only opponent, a filly named Schumla. The runner-up lost any chance of creating an upset when she ran wide on the turn into the straight after being distracted by the presence her trainer, mounted on his
hack on the outside of the course. Charlotte West was off the course for almost five months before returning on 6 November, the last day of racing at Newmarket in 1830. She was assigned top weight of 126
pounds in a five
furlong handicap race in which she was matched against colts and older horses. She was ridden by George Edwards, and started the 5/2 favourite, whilst her main rival, Mr Rush's unnamed colt by
Tiresias out of
Rhoda was ridden by Jem Robinson. Charlotte West won by a head from the Rhoda colt, with Edwards reportedly riding a particularly fine race.
1831: four-year-old season Charlotte West was kept in training as a four-year-old but failed to reproduce her earlier success. At the First Spring meeting at Newmarket on 18 April she started 6/5 favourite for a five furlong handicap, but finished third of the four runners behind Mr Cooke's colt Harold. At the next Newmarket meeting in May she ran a £50 match against Zillah in which she attempted to concede five pounds to the 1000 Guineas runner-up. Charlotte West was favoured in the betting but beaten in the race and did not compete again. ==Stud record==
