Shigeru So

Shigeru So (宗茂, Sō Shigeru) (born 9 January 1953 in Usuki, Ōita) is a Japanese retired long-distance runner who represented his native country at two Summer Olympics: 1976 and 1984. He won the 1985 edition of the Tokyo Marathon. His twin brother Takeshi So is also a retired Olympic marathoner, and finished fourth in Los Angeles, California (1984).

Some road racing authorities consider his winning run at the Beppu-Ōita Marathon in 1978 (2:09:05.6) to have been a marathon world best.^{[nb 1]}

^ The International Association of Athletics Federations has published a progression of road racing world bests and records that were widely recognized prior to ratification and official acceptance by the IAAF. According to that progression, Derek Clayton's 2:08:34 performance in Antwerp on 30 May 1969 was a world best at the time.^[1] Other road racing authorities, including the Association of Road Racing Statisticians, consider Clayton's performance to have occurred on a short course and recognize other athletes in the progression for world best in the marathon.^[2]
