The 1927 Grand National was the 86th renewal of the Grand National horse race that took place at Aintree near Liverpool, England, on 25 March 1927. The race was won by Sprig, the 8/1 favourite ridden by jockey Ted Leader. Leader's father, Tom, trained the winner. It was Sprig's third attempt at winning the National — his owner, Mary Partridge, having kept him in training in memory of her son who died in World War I. This was the first National to be covered on BBC Radio.
