Kanakuri

Shisō (四三) Kanakuri (金栗), 1891–1983, was a Japanese marathon runner celebrated as the "father of marathon" in Japan. He holds the Guinness World Record for the longest time to complete a marathon. In November 1911, at the age of 20, Kanakuri raced in the domestic trials for the 1912 Stockholm Olympics where he reportedly set a marathon world record at 2 hours, 30 minutes and 33 seconds, although the course was just 40 km (25 mi). He was selected as one of the two Japanese athletes to attend the event.
