DAYTONA BEACH, FLA.—This past weekend, much of the world's racing fraternity turned out for the annual Rolex 24 endurance race at Daytona International Speedway. First held in 1962, the race around the clock on a 3.5-mile (5.6km) mix of 31-degree banking and flat infield is probably IMSA's highest-profile event and one of the toughest 24-hour races on the calendar. 2019's event was no cakewalk, particularly once Mother Nature showed up to spoil the party.
