Hunter-Reay takes breaths seriously. Free diving has taught him how to fill not only his lungs, but also his throat and mouth with oxygen in order to maximize his time underwater. He has learned to expand his inhalations by trying to let air into his gut in the manner of an opera singer. And, yes, he's quick to point out, this makes a difference on the track. "In racing, you end up feeling up to 4 g's in the corners," he explains. "When your chest is under that pressure, you can't breathe. Not a big deal at Indy, but it can become an issue when you have a road course with a bunch of corners in succession." Hunter-Reay is known for winning on street courses.
