Bruce became famous after winning the gold medal for the decathlon at the 1976 Olympic summer games. The ensuing success led to acting roles and even an audition to star in the first Superman movie.
In an interview with Parade, Bruce joked that his legacy will likely be starring with wife Kris Jenner and her daughters in reality shows.
"There's a huge audience who only know me as Kim [Kardashian's] stepdad, which is fine. Being a dad is more important than winning the Olympic Games," he said.
Bruce added that he does look back fondly on his years as an Olympic stand-out.
"The Games are so unique - you take on the world," he explained, adding: "Reality TV is not that big a deal, but it does bring you fame."
The London Olympic Games kick off on Friday, July 27 with Danny Boyle's 'Isles of Wonder' opening ceremony.
