even trained with his rival Otto Peltzer. Nurmi told Peltzer to forget his opponents: "Conquering yourself is the greatest challenge of an athlete." Nurmi was known to emphasize the importance of psychological strength: "Mind is everything; muscle, pieces of rubber. All that I am, I am because of my mind." Regarding Nurmi's track antics, Peltzer found that "in his impenetrability he was a Buddha gliding on the track. Stopwatch in hand, lap after lap, he ran towards the tape, subject only to the laws of a mathematical table." Marathoner Johnny Kelley, who first met his idol at the 1936 Olympics, said that while Nurmi appeared cold to him at first, the two chatted for quite a while after Nurmi had asked for his name: "He grabbed ahold of me — he was so excited. I couldn't believe it!" Nurmi's speed and elusive personality led to nicknames such as the "Phantom Finn", the "King of Runners" and "Peerless Paavo", while his mathematical prowess and use of a stopwatch led the press to characterize him as a running machine. One newspaperman dubbed Nurmi "a mechanical Frankenstein created to annihilate time." Phil Cousineau noted that "his own innovation — the tactic of pacing himself with a stopwatch — both inspired and troubled people in an era when the robot was becoming symbolic of the modern soulless human being." Among the popular newspaper rumours about Nurmi was that he had a "freakish heart" with a very low pulse rate. During the debate over his amateur status, Nurmi was joked to have "the lowest heartbeat and the highest asking price of any athlete in the world." Legacy Nurmi broke 22 official world records on distances between 1500 m and 20 km; a record in running. He also set many more unofficial ones for a total of 58. His indoor world records were all unofficial as the IAAF did not ratify indoor records until the 1980s. Nurmi's record for most Olympic gold medals was matched by gymnast Larisa Latynina in 1964, swimmer Mark Spitz in 1972 and fellow track and field athlete Carl Lewis in 1996, and broken by swimmer Michael Phelps in 2008. Nurmi's record for most medals in the Olympic Games stood until Edoardo Mangiarotti won his 13th medal in fencing in 1960. Time selected Nurmi as the greatest Olympian of all time in 1996, and IAAF named him among the first twelve athletes
