LAS VEGAS — Which was tougher: qualifying for the Indy 500, jetting to partake in the Monaco Grand Prix and then zipping back to race in the 500, or completing all 1,100 miles of the 500 and Coca-Cola 600 the same day?
Sir Jackie Stewart accomplished the former during a 16-day stretch in 1966 in which he won Monaco and nearly won Indy. On May 27, 2001, Tony Stewart achieved the latter. Nobody else has pulled off either feat.
