Athletics at the 1964 Summer Olympics – Men's marathon
The men's marathon was part of the Athletics at the 1964 Summer Olympics program in Tokyo. It was held on 21 October 1964. 79 athletes from 41 nations entered, with 68 starting and 58 finishing. The maximum number of athletes per nation had been set at 3 since the 1930 Olympic Congress. The event was won by Abebe Bikila of Ethiopia, the first man to successfully defend Olympic gold in the marathon (and, indeed, the first to win two medals of any color in Olympic marathons). Unlike in 1960, he wore shoes this time. Great Britain earned its first marathon medal since 1948 with Basil Heatley's silver; Japan took its first medal since 1936 with bronze by Kōkichi Tsuburaya.
