On Sunday, for the ninth time, a driver will attempt to race both the Indianapolis 500 and the Coca-Cola 600 on the same day.

Kurt Busch is the latest to sign up for this most daring of double-duty, driving at Indy for Andretti Autosport. Green flag is at noon (ET) for open-wheel’s biggest race. Later Sunday afternoon he’ll jet down to Charlotte to jump into his No. 41 Haas Automation Made in America Chevrolet for the 6 p.m. (ET) start of NASCAR’s longest race.

The eight previous double-dips have been divided up by only three drivers – John Andretti (1994), Robby Gordon (1997, 2000, ’02, ’03, ’04) and Tony Stewart (’99 and ’01). Stewart has the best result – by far – in the books, having finished sixth at Indy and third at Charlotte in 2001, in the process becoming the only driver to complete all 1,100 miles between the two races.

Busch qualified 10th for the Indianapolis 500, but crashed in a Monday practice session and will be forced to a back-up car.
