Michael Page was educated at the Briar Cliff High School (New York) and École de Commerce in Neûchatel, Switzerland. His first international Three Day Event was the 1959 Pan-American Games when he won the individual event and led the U.S. to the silver medals in the team event. He made his Olympic debut in 1960 when he placed a disappointing 17th but, before his second Olympic appearance, he again won the Pan-American title (1963) and was a member of the team which took the gold medals in the team competition. At the 1964 Olympics, Page placed fourth in the individual competition and won a silver medal in the team event. At his third Pan-American Games in 1967, Michael Page again won a gold medal in the team event and placed third individually. In his third, and final, Olympic appearance in 1968, he won a silver medal in the team event and a bronze in the individual. He later coached the 1976 Canadian Olympic Three-Day Event team.
