Stewart opts to not run in Indy 500

CHARLOTTE, N.C. -- Tony Stewart made his double-duty plans official Monday, saying he will not drive in the Indianapolis 500.

Stewart, a former Indy Racing League champion, will only compete in the Coca-Cola 600 and not make a third attempt at the grueling 1,100-miles of racing. He cited his desire to win the Winston Cup championship this year and his shot at a $1 million bonus if he wins the 600 for not entering the Indy 500.

"Running Indy again is something I've put a lot of thought into, but when it came right down to it, the long-term goal of winning the Winston Cup championship won out," Stewart said.

"We are in the No Bull 5, and that means a $1 million bonus if we win. By not running Indy, we'll start where we'll qualify and not at the back of the field."

Stewart is 12th in the Winston Cup standings, 204 behind leader Sterling Marlin. But he's been strong all season and an engine problem in Daytona and a wreck at Darlington dropped him back in the standings.

Stewart has made no secret of his desire to win the Indy 500. He's the only driver to ever finish double duty, completing the fete last year when he finished sixth at Indy and third in the 600 later that night.
