Attempting to complete 1,100 miles in a single day of racing is quite the challenge (unless you're an endurance racing driver), but it's even more daunting when you're doing it in two wildly different race cars and at two race tracks that are multiple states apart.
That is what it means when a driver like Kyle Larson says they are attempting 'The Double.' They start their day at Indianapolis Motor Speedway for the Indy 500 around 12:45pm EST, and then end their day around 11pm EST at Charlotte Motor Speedway when NASCAR's longest race -- the Coca-Cola 600 -- reaches its conclusion.
