Tony Stewart not planning more doubles

CONCORD, N.C. -- It's been 10 years since Indiana native and NASCAR Sprint Cup driver Tony Stewart last pulled off the Indianapolis 500-Coca-Cola 600 double.

Don't expect it to happen again.

"In my heart? Absolutely, I would love to do it," Stewart said. "The problem with it is that IndyCars have become so competitive now."

Stewart, who turned 40 earlier this month, competed in both races the same day in 1999 and 2001. He became the only driver to post two top-10 finishes despite thinking that he might be hallucinating during the last 100 miles at Charlotte 10 years ago.

"Obviously, I'm not Mr. Olympia and I'm not the healthiest guy in the world compared to a lot of other drivers on the circuit," Stewart said. "By the time the 600 was done, I'd had enough. I was hungry 50 laps into the race.

"It was still early and there wasn't a Burger King drive-thru in sight."

But that's not the main reason the NASCAR Sprint Cup driver and owner thinks racing the Indianapolis 500 again is unlikely.

"There are so many things that have changed since I ran Indy cars so many years ago," he said. "I'm not sure I would be up to speed and be able to get competitive enough quickly enough.

"I have all the confidence in the world the cars I would drive would be competitive. But to really do it and do it right and to feel like you have a legitimate shot to win the Indy 500, you would have to start at the beginning of the year with the team you're going to race with during the month of May."

Stewart was still able to race in different circuits over the weekend. A night before the Coca-Cola 600, Stewart finished 10th in a sprint car race on the dirt track next to Charlotte Motor Speedway.
