Paavo Johannes Nurmi (; 13 June 1897 – 2 October 1973) was a Finnish middle-distance and long-distance runner. He was called the "Flying Finn" or the "Phantom Finn", as he dominated distance running in the 1920s. Nurmi set 22 official world records at distances between 1500 metres and 20 kilometres, and won nine gold and three silver medals in his 12 events in the Summer Olympic Games. At his peak, Nurmi was undefeated for 121 races at distances from 800 m upwards. Throughout his 14-year career, he remained unbeaten in cross country events and the 10,000 metres. Born into a working-class family, Nurmi left school at the age of 12 to provide for his family. In 1912, he was inspired by the Olympic feats of Hannes Kolehmainen and began developing a strict training program. Nurmi started to flourish during his military service, setting Finnish records in athletics en route to his international debut at the 1920 Summer Olympics. After winning a silver medal in the 5000 m, he won gold in the 10,000 m and the cross country events. In 1923, Nurmi became the first runner to hold simultaneous world records in the mile, the 5000 m and the 10,000 m races, a feat which has never been repeated. He set new world records for the 1500 m and the 5000 m with just an hour between the races, and took gold medals in both distances in less than two hours at the 1924 Summer Olympics. Seemingly unaffected by the Paris heat wave, Nurmi won all his races and returned home with five gold medals, although he was frustrated that Finnish officials had refused to enter him for the 10,000 m. Struggling with injuries and motivation issues after his exhaustive U.S. tour in 1925, Nurmi found his long-time rivals Ville Ritola and Edvin Wide ever more serious challengers. At the 1928 Summer Olympics, Nurmi recaptured the 10,000 m title but was beaten for the gold in the 5000 m and the 3000 m steeplechase. He then turned his attention to longer distances, breaking the world records for events such as the one hour run and the 25-mile marathon. Nurmi intended to end his career with a marathon gold medal, as his idol Kolehmainen had done. In a controversial case that strained Finland–Sweden relations and sparked an inter-IAAF battle, Nurmi was suspended before the 1932 Games by an IAAF council that
