Who is the leading owner in the history of the Cheltenham Gold Cup?  Unsurprisingly, the leading owner in the history of the Cheltenham was the owner of the most successful horse in the history of the ‘Blue Riband’ event, Golden Miller. Golden Miller achieved legendary status by winning the Cheltenham Gold Cup five years running between 1932 and 1936, but his owner, the Honourable Dorothy Paget, became almost as famous, or infamous, for her eccentric, often tyrannical behaviour. The richest unmarried woman in the country, at one point, Miss Paget would win the Cheltenham Gold Cup again with Roman Hackle in 1940 and Mont Tremblant in 1952, for a total of seven victories; her success did not prevent her being utterly difficult and falling out with her trainers on a regular basis.

Basil Briscoe, who trained Golden Miller to win the Cheltenham Gold Cup the first four times, was replaced by Owen Anthony after the horse tried to refuse and unseated rider in 1935 Grand National. Anthony, who also trained Roman Hackle, was sufficiently forthright to tell the largely nocturnal not to disturb him in the middle of the night, as was her custom. Fulke Walwyn, who trained Month Tremblant, on the other hand, found Miss Paget ‘so trying’.
