In the 1955/56 National Hunt season he was the leading staying chaser in Britain winning both the King George VI Chase and the Cheltenham Gold Cup.
Dutton first came to fame as an amateur jockey by riding Tipperary Tim to victory in the 1928 Grand National and later became a very successful trainer of both flat horses and jumpers.
[3] In the following season Limber Hill made further progress and defeated Gay Donald at Manchester Racecourse in November[8] before establishing himself as one of the best staying chasers in Britain in the King George VI Chase at Kempton Park.
[9] In the month preceding the 1956 Cheltenham Festival many meetings were abandoned because of frozen ground and Dutton kept Limber Hill fit by galloping him on the beach at Filey.
Power made a forward move approaching the third last and Limber Hill jumped past Cruachan at the next fence to take the lead before going clear.
[13] In late 1956 Limber Hill was beaten on heavy ground in the Emblem Chase at Aintree Racecourse[14] and then injured his back when preparing for an attempt to win the King George for a second time.
