You might think sitting behind the wheel for a few hours is an easy way to earn a living, but you'd be wrong. Endurance racing in particular requires the ability to focus at almost superhuman levels for hours while fighting heat, g forces, the effort of driving the car, and, of course, the rest of the drivers on the track.

This video details how Oliver Gavin, Corvette Racing driver, and Ken Flory, chief engineer, train to be able to take the strain on the track and behind the pit wall. It's a look inside the life of a race driver we don't often get in road racing, and well worth the three minutes for a true enthusiast or anyone that dabbles in amateur racing on their own.
