Which horse is the only three time winner of the Grand National, at Aintree in England?

Red Rum (bay gelding; 3 May 1965 – 18 October 1995) was a champion Thoroughbred steeplechaser. He achieved an unmatched historic treble when he won the Grand National in 1973, 1974 and 1977, and also came second in the two intervening years (1975 & 1976). The Grand National is a notoriously difficult race that has been described as "the ultimate test of a horse’s courage". He was also renowned for his jumping ability, having not fallen in 100 races.

Red Rum's 1973 comeback victory from 30 lengths behind is often considered one of the greatest Grand Nationals in history. In a 2002 UK poll, Red Rum's historic third triumph in the Grand National was voted the 24th greatest sporting moment of all time.

Reynoldstown won the race in 1849 & 1853.

The Colonel won the race in 1935 & 1936.
