Arthur Lydiard is probably the most successful and influential running coach of the 20th century. In 1960 he burst into prominence at the Rome Olympics when two of his proteges, Peter Snell and Murray Halberg, won Olympic gold medals on the same day. He had turned unpromising athletes into Olympic champions, and he said he could repeat the feat if only his methods, which involved building stamina and fitness through endurance running, were followed. In the next few years thousands of people heeded his word. The jogging movement was born.
