Answer
Bob Mathias and Daley Thompson are the other two Olympians to win back-to-back decathlon gold medals. Mathias won the decathlon at the 1948 and 1952 Summer Olympics, while Thompson won the decathlon at the 1980 and 1984 Summer Olympics. Mathias was the first American to win the decathlon at two consecutive Olympics, and Thompson was the first British athlete to do so.
