James was brought up in a family surrounded by the tradition of owning, breeding, training and riding horses. He ran the Adstock Manor Stud in England for 25 years during which time the farm raised the winners of 29 international Group races.

These include the Epsom Oaks and King George V1 and Queen Elizabeth Diamond Stakes winner Time Charter and triple Group 1 winner Master Willie. Influential broodmare sire High Line stood at Adstock throughout his career.
One of the biggest challenges James took up in the early eighties was the setting up of Juddmonte Farms in England, Ireland and the USA for HRH Prince Khalid Abdullah. The construction of Juddmonte Farms has been widely praised as the ultimate in aesthetic appeal allied to practical and efficient design, and won for James an award from the New York Association of Architects.

The success of Juddmonte Farms owes much to James’s expertise in assembling the broodmares which are now yielding a bountiful harvest including two Epsom Derby winners, and at least one winner of all five English classic races. The sire and dam of both Juddmonte’s Derby winners were purchased for the farm by James.
