The ultimate sporting great to my mind is from another era totally; CB Fry. Some no doubt will know the name, but to many he is a virtual unkown.
He played internationals (for England) at footy and cricket and was a very competent rugby player (Barbarians). He set a world record for the long jump and could, into hs seventies, jump from a standing start backwards onto a mantelpiece.
He also foud time to stand as a candidate for parliament, losing two or three elections.
Off the sporting pitch he set up magazines, helped establish the League of Nations, and alledgedly was asked to become king of Albania. A newspaper columnist, a radio cricket commentator in his later years he was also involved in eduation. He met Hitler, and rather worringly, invited members of the Hitler Youth to one of his training establishments.
What a life.
