NASCAR is a sport known for speed and endurance. Racers spend upwards of 1 to 2 hours racing around the track in a constant chase for victory. The Sprint Cup is one of NASCAR’s most important races – kind of like the World Series of racing. It might shock you to find out that despite those hours of endurance, the line between victory and defeat is often fractions of a second thin! The closest finish in history took place in 2003, when the first and second place finishers were just 0.002 seconds apart. Take a look at how close some of the other finishes were, and relive these classic races!
