Yuki Kawauchi

Yuki Kawauchi, born 5 March 1987 in Setagaya, Tokyo, is a Japanese marathon runner who came to prominence by running the 2011 Tokyo Marathon in 2:08:37, finishing as the first Japanese citizen and third overall. He was known as the citizen runner because he worked full time for the government of Saitama Prefecture and trained in his own time without sponsorship, and he left that job in 2020 to run professionally. He won the 2018 Boston Marathon, the Hokkaido Marathon and the Beppu-Oita Marathon, and he races often, averaging about a marathon a month at distances from the 1500 m up to a 50 km ultramarathon. Guinness World Records recognized him as the first person to run more than 100 marathons under 2:20.
