A proper runner and, like Bill Adcocks, still involved in the sport as I understand.
I was driving my son and 2 friends home from cubs, they were about 7. They had been playing statues and one of them said "You couldn't have won if you were the fastest man in the world." So I said "OK, who of them is the fastest man in the world" to see if they knew Usain Bolt and one of them said "I don't know but I think my Grandad used to be." "Who's you Grandad then?" "Jim Alder!"
It was a huge long shot I knew who he was but great for Jim's grandson I did, and thought he was a legend. If he was that good and played football he would be a household name.
