Thirty-one-year-old Chad Mackay took first place in the Pendleton 2 event at this year's CrossFit Games. The 225-pound athlete missed out on the Games in 2011 due to an injury, and says he's happy to be back.

"To win the CrossFit Games would be amazing," he says.

Outside of CrossFit, Mackay enjoys surfing, practicing yoga and hanging out with friends and family down under in his hometown of Sydney, New South Wales. 

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