[7] La Roche was matched against male opponent in the British Dominion Two-Year-Old Race over five furlongs at Sandown Park on 24 June but after showing good early speed she came home last of the five runners behind Stealaway.

[10] At Epsom Racecourse on 1 June La Roche, with Cannon again in the saddle, started the 5/1 third choice in the betting behind Winifreda and Lady Schomberg in a fourteen-runner field for the 122nd running of the Oaks Stakes.

She took the lead a quarter of a mile from the finish and drew away to win very easily by three lengths from Merry Gal, with Lady Schomberg coming home a distant third.

[11] The Oaks form received a boost on 5 July when Merry Gal scored an upset victory over Diamond Jubilee in the Princess of Wales's Stakes at Newmarket.

[15] La Roche had never been entered in the St Leger, for which she might well have started favourite,[15] and so was instead matched against older horses in the two and a quarter mile Doncaster Cup on 14 September at the same meeting.

Despite carrying a ten pound weight penalty she started 5/6 favourite but after leading into the straight she was overtaken and beaten into third place behind King's Courier and Merry Gal.
