Guido Kratschmer (pronounced as /de/; born 10 January 1953 in Klotzenhof, West Germany) is a retired West German decathlete. His sports club was the USC Mainz.
Kratschmer competed at the 1976 Summer Olympics in Montreal, where he won the silver medal in the men's decathlon event. He could not participate at the 1980 Summer Olympics because of the boycott.
In 1980, Kratschmer broke the world record held by Daley Thompson, but in 1982, Kratschmer's mark was in turn topped by Thompson.
Kratschmer's personal best total in the decathlon was 8667 points, achieved in June 1980 in Bernhausen, West Germany. This total ranks him sixth all-time among German decathletes, behind Jürgen Hingsen, Uwe Freimuth, Siegfried Wentz, Frank Busemann and Torsten Voss.[1]
