John Smith

John Walton Smith is a former American athlete, who competed in the sprints events during his career. He is best known for winning the 400 m event at the 1971 Pan American Games. He remains the world record holder for the 440 yard dash at 44.5 seconds. He set the record while winning the USA Outdoor Track and Field Championships on June 26, 1971 while running for the Southern California Striders. The record has stood since then due to metrification in the sport. Contemporary athletes rarely run or are timed officially for the extra 2.34 meters to equal 440 yards.
