Lydiard’s first students were young men from Arthur’s Auckland suburb of Owairaka, who, without exception, rose to national and international prominence in the athletic arena. His most notable successes were with Olympic gold medalists Peter Snell, (800m -1960, 800m & 1500m -1964); Murray Halberg, (5000m -1960); and bronze medalists, John Davies (1500m -1964); and Barry Magee (Marathon -1964).
In the 1960’s, Lydiard began to influence other coaches around the world working with Budd Winter in Mexico and spending time in Finland, where the coaches of Lasse Viren and Pekka Vasala implemented his ideas. It was in 1972, four years after working with Lydiard, that Viren won Olympic Gold in the 5,000m and 10,000m with a world record in the 10k, and Vasala won gold in the 1500m.
Arthur later influenced coaches to the second generation of New Zealand Olympic medal success, including John Walker (1500m gold medal -1976) coached by Arch Jelley, Dick Quax, (5000m silver medal -1976) coached by John Davies, Rod Dixon, (1500m bronze medal -1972) coached by his brother, John Dixon, and Lorraine Moller (bronze medal -1992) coached by Dick Quax.
