NASCAR races generally last anywhere from 1.5 to 4 hours, depending on the length of the race, number of laps and track conditions. Many races are 500 miles in length, though some are shorter or longer.
Normal track conditions at a recent Daytona 500 resulted in a total race time of three hours, 26 minutes and 29 seconds for the 500-mile race. The number listed after the official race name designates either the number of track laps or the mile distance to complete the event.
