In 1950, at the age of 18, John took up boxing in Buxton, and earned a total of £17 at prize-fights in his local Town Hall. He did not much enjoy boxing, but found during his training that he had a talent for long-distance running. Accordingly, he gave up boxing the following year and turned his sights to training for the marathon, hoping to compete at the
1960 Summer Olympics in Rome, Italy. In 1952 John applied to join the
Salford Harriers in order to register with the
Amateur Athletic Association of England. On being asked whether he had ever played sport for money, he chose to answer honestly and declared his brief career in prize-fighting. Due to the strict
amateur code enforced at the time, he was immediately banned from competition for life. In the 1960s he turned to
ultra-marathons, and set world records for 40-mile and 100-mile distances. In 1967 he became the first man ever to win the season's grand slam in Britain's four principal ultra-marathons (the
London-to-Brighton, Isle of Man, Exeter-to-Plymouth, and Liverpool-to-Blackpool). While participating in the 90 km
Comrades Marathon in South Africa in 1968 (in which he finished fourth), he became aware of the
apartheid conditions there, and (as a white man) began to enter the first ever "multi-racial" races there as a form of support, notably winning the 80 km Goldtop Stanger-to-Durban race in 1970. == Career wins and world records ==
