The New Zealander Arthur Lydiard was the most successful trainer of middle and long distance running in the world. He coached runners from different countries such as Peter Snell (3 times gold) or Lasse Viren, who reached 4 times gold. In the 50s and 60s Arthur Lydiard not only revolutionized the middle and long distance training but parallel to this development he may be considered as one of the founders of the jogging-movement.
