Racing career
Jay Trump's early race record was unremarkable; Jay Trump ran 8 times, with one second-place finish, earning $220. In 1960, amateur steeplechase jockey, Crompton "Tommy" Smith, purchased Jay Trump for Mary Stephenson, who was a family friend. He was purchased as a steeplechase prospect. Tommy Smith was the grandson of the great sportsman and steeplechase racer Harry Worcester Smith, who in 1912 and 1913 traveled to Ireland, England and France as the invited "Master of the Westmeath Hounds." Jay Trump won his first race in 1962. In 1963 he won his first Maryland Hunt Cup, setting a course record, defeating Mountain Dew. Plans were hatched to take Jay Trump to England for the Grand National, but it was thought better to wait another year. Jay Trump won the Maryland Hunt Cup for a second time in 1964, again defeating Mountain Dew. Later that year he was shipped to England. He won his first race for trainer Fred Winter at Sandown on October 21, 1964; this was also the first winner for the trainer. Jay Trump went on to win two more races and finished second in the King George VI Chase, as he prepared for the Grand National. In 1965 Jay Trump won the English Grand National, defeating Freddy in a remarkable battle to the line. He was the first Maryland Hunt Cup horse to win the Grand National, as well as the first American owned, bred and ridden winner of the Grand National. Since that time, Ben Nevis II has repeated the feat of winning the Maryland Hunt Cup in 1977 and 1978, and the Grand National in 1980. After his Grand National victory, Jay Trump went to France to run in the Grand Steeplechase. He was made the favorite, but finished third to Hyeres III, who had also won the race in 1964. Jay Trump then returned to the United States, where he ran in one more Maryland Hunt Cup, in 1966. He won that race, and was promptly retired. Mountain Dew was second to Jay Trump in this race for the third time. Mountain Dew also won three Maryland Hunt Cup races; Jay Trump and Mountain Dew formed a tremendous rivalry in the 1960s.
