Chris Spealler is the only athlete to compete in all six CrossFit Games. The 33-year-old has been called a legend among the CrossFit community.

"I think I'm always the underdog ... no one gave this me ... I earned every bit of it," he says.

Spealler announced that 2012 would be his last year competing in the CrossFit Games.

"Because I’m going into it with the intention of it being my last year ... I’m gonna enjoy it, I'm gonna go down guns blazing."

The 2012 Reebok CrossFit Games will re-air on ESPN2 starting Dec. 16.
