Jean-Jacques Guyon surprisingly won the individual three day event at the 1968 Mexico City Olympics aboard Pitou, finishing fourth in the team event. He was then the French flagbearer at the Closing Ceremony. Guyot also won the French national title in 1965, won a team bronze medal at the 1957 European Championships, and was World Military Champion in 1969.
Guyon was a career soldier, who first served in the rank of Chief Warrant Officer and was a master at the famous Cadre Noir in Saumur, where he married in 1964. He later taught at the Saint Cyr-Coëtquidan Military School (1964-66), and then at the National Center of Equestrian Sports (1966-69), before becoming a technical adviser for riding, working for Gilbert Trigano, with Club Méditerranée until 1987.
