James Henry Peters was a long-distance runner from England. He broke the world record for the men's marathon four times during the 1950s. He was the first runner to complete a marathon in under 2 hours 20 minutes; the Association of International Marathons and Distance Races has compared the significance of that barrier to the four-minute mile. Jim Peters (United Kingdom) set the men's marathon world record of 2:20:42.2 in Polytechnic Marathon on June 14, 1952. It stood 12 months, until Jim Peters's 2:18:40.4 on June 13, 1953. Wiki link
