Cheltenham Gold Cup races from 1932 to 1936 were won by Golden Miller, who also won the Grand National in 1934. During World War II the Gold Cup was cancelled twice, in 1943 and 1944. The first multiple winner of the post-war years was Cottage Rake, who won the three runnings from 1948 to 1950. Cottage Rake was trained in Ireland by Vincent O'Brien, and his successes helped to popularise the Gold Cup, and the Festival itself, with the Irish public. The Gold Cup was switched to the "New Course" in 1959, and this is now the regular track used for the event.
Welsh Grand National win the Welsh and Aintree Nationals. In the late 80s and early 90s, the race was dominated by Somerset trainer Martin Pipe. Bonanza Boy achieved consecutive successes in 1988 and 1989, and in 1991 the giant Carvill's Hill became one of the easiest winners in the history of the race. More recent winners of both the Welsh and the Aintree Grand National are Bindaree and Silver Birch. The 2010 winner, Synchronised, went on to win the 2012 Cheltenham Gold Cup. The 2016 winner Native River, ridden by champion jockey Richard Johnson, went on to win the 2018 Cheltenham Gold Cup.
