The Rolex 24 at Daytona marks IndyCar driver Scott McLaughlin's first road trip — and first race — since becoming a father in October.

Daytona's annual sports-car run, the Rolex 24, began in 1962 as a 3-hour effort. It's been won by Mario Andretti and Paul Newman, among other stars.

The group of five Chevrolet Corvette Z06 GT3.Rs set for the season-opening Rolex 24 At Daytona completed their three days of testing at Daytona International Speedway on Sunday with the four teams focused ahead to next weekend’s twice-around-the-clock classic.

Sunday's final day of Rolex 24 testing could be a wet one. The five-day race week begins Wednesday, and the weatherman wants to have a word with you.
