Few things in sport are more thrilling than a great racehorse giving its all. That’s why the death of that noble steeplechaser Many Clouds on Saturday was so sad, so epic too. Courage is an over-used word in sport, but Many Clouds really was very brave indeed. He won the Grand National on strength-sapping ground in 2015, and at the weekend fought back to beat the best chaser of the present day, Thistlecrack, by a head.
