Chip Ganassi owns a unique and impressive record: He's the only team owner to win the Indianapolis 500, the Daytona 500, the 24 Hours of Le Mans and the Rolex 24.

Ganassi's fleet of Ford GTs triumphed in their class last weekend at Le Mans, a historic victory given that came 50 years after the first time Ford defeated Enzo Ferrari at the French endurance race.

But Ganassi, who is now 58, found out the hard way that the demands of a 24-hour race aren't as much fun as they might have been in his younger days.

"I actually slept for about two-and-a-half or three hours on Saturday night, but you wake up on those Sunday mornings of 24-hour races and its kind of like being back in college," said Ganassi.

"You're just in a stupor and you weren't even drinking the night before, but you're in a stupor from getting no sleep and you're going through the motions of everything and you don't really remember much," he said.

And it took some time for the enormity of his accomplishment to sink in as a result.

"It wasn't until Tuesday when I woke up in my own bed in Pittsburgh that I was pinching myself saying, 'Did that really just happen?'" he said.

The good news is, yes, indeed, it really did happen.

"It was a huge effort by our team and it was really an honor to participate in that event," Ganassi said of Le Mans. "It's such a traditional thing. It's not unlike Daytona or Indy in terms of tradition and history."
