Ryan Hunter-Reay: Free Diving
"After about two days on vacation, I just get so bored," the 2014 Indy 500 champ admits. "I think it's because of the intensity of the sport." So Hunter-Reay seeks his offseason thrills by free-diving off the coast of his home state of Florida. He has since gone 60 feet below the surface. An added bonus: He uses the deep-sea breathing techniques when he's pitching around corners in his car, to help alleviate the pressure on his chest.
