As a young horse Chatelaine was extremely nervous and restless but her temperament improved when she was introduced to "Billy", a goat who became her constant companion.
[8] In the spring of 1933 Chatelaine contested the 1000 Guineas over the Rowley Mile at Newmarket Racecourse on 28 April and ran creditably to finish seventh of the twenty-two runners in a race which saw Brown Betty win from Fur Tor and Myrobella.
[4] On her first appearance after her Epsom victory, Chatelaine was dropped back in distance for the Coronation Stakes over one mile at Royal Ascot and finished unplaced behind Betty.
[9] At York Racecourse in September Chatelaine finished second to the Epsom Derby runner-up King Salmon in the Great Yorkshire Stakes over fourteen furlongs.
Ridden by Gordon Richards she dead-heated for first place with the Aga Khan's four-year-old colt Dastur after what was described as a "great duel", with the advantage passing back and forth over the last quarter mile.
[11] In the Jockey Club Cup on two weeks later she was tried over two and a quarter miles and finished second of the three runners, beaten one and a half lengths by Nitsichin, a five-year-old mare whose wins included the Irish Oaks and the Cesarewitch.
[13] Chatelaine's earnings of £8,170 in 1933 made her the fifth most financially successful racehorse in England behind Hyperion, Colombo, Loaningdale (Eclipse Stakes) and Rodosto (2000 Guineas).
