Kenyan Eliud Kipchoge may already be the best marathoner in history. In Tokyo, at the last Olympics, Eliud Kipchoge joined a very closed circle. He became the third athlete to retain his title of Olympic marathon champion. Only the Ethiopian Abebe Bikila (1960 and 1964) and the German Waldemar Cierpinski (1976 and 1980) had achieved this feat before him. Kipchoge is also the holder of the world record for the marathon (2h1min39 s). He managed to complete the 42 km "in less than two hours", but unfortunately this time was not approved by World Athletics because it was not an official race.
