Darrell Waltrip is set to retire from NASCAR racing, but not before a farewell tour in 2000.

The three-time Winston Cup champion leads active Winston Cup drivers with 84 victories, but has not won a race in seven years.

Waltrip and team sponsor Kmart will announce the move Thursday during the opening day of practice and qualifying for the Brickyard 400 at Indianapolis Motor Speedway.

His final season apparently will be modeled after the recent retirement tours of Richard Petty, Mario Andretti and Bobby Rahal, all of whom tied their farewells to marketing campaigns.

Waltrip was not available to comment yesterday, but personal representative Keith Waltz said the announcement will be "no surprise to anybody."

Waltrip signed a two-year contract with team owners Travis Carter and Carl Haas last fall. At the time, he said it would be his last as a driver.

"Darrell hasn't made any secret of his plans," Carter said.

Atwood got his second pole in the last four races with a lap of 132.423 mph, beating out Jeff Green, who ran the 1.25-mile track at 132.302 mph.
