Keysoe (horse)

Keysoe was a brown mare reportedly standing 17 hands high[2] bred in England by her owner Edward Stanley, 17th Earl of Derby.

At Goodwood Racecourse on 29 July she recorded her first success as she won the Gratwicke Stakes "in a canter" by eight lengths[6] from Britannia and Misty Morning.

[9] On 10 September Keysoe was moved up in class to contest 144th running of the St Leger Stakes over 14+1⁄2 furlongs in at Doncaster Racecourse.

[10] The crowd included the 85-year-old ex-jockey John Osborne who won the race on Lord Clifden and Apology and was attending his 66th St Leger.

[11] Ridden by the Australian jockey Bernard "Brownie" Carslake Keysoe started at odds of 100/8 (12.5/1) against nine opponents including Buchan who had finished runner-up in both the 2000 Guineas and the Epsom Derby and started 8/11 favourite ahead of the Prince of Wales's Stakes winner Dominion and the Irish challenger Cheap Popularity.

In May she finished second to Kentish Cob in the Burwell Stakes at Newmarket[16] and was then beaten by the colt Our Stephen (her only opponent) in the Great Northern Handicap at York.
