[3] During his racing career, Red Splash was owned by Major Humphrey Wyndham and was trained by Fred Withington at Fritwell in Oxfordshire.
[5] Red Splash showed early promise as a steeplechaser and won four times over fences in the 1923/1924 National Hunt season including a race at Cheltenham Racecourse in November.
In the spring, he was entered in the inaugural Cheltenham Gold Cup in which, as a five-year-old, he carried nine pounds fewer than his older opponents.
The final stages saw a sustained three-way struggle as Red Splash fought off strong challenges from Conjuror and Gerald L to prevail by a head and a neck.
[8][5][9] Following his victory at Cheltenham, Red Splash was highly regarded, being described as showing "marked dash in leaping his fences" and likely to become a leading Grand National contender.
