The Coca-Cola 600 is an annual 600-mile (965.606 km) Monster Energy NASCAR Cup Series points race held at the Charlotte Motor Speedway in Concord, North Carolina, during Memorial Day weekend. The event, when first held in 1960, became the first race to be held at the Charlotte Motor Speedway. Run since 1960, it is the longest race on NASCAR's schedule at 600 miles (970 km). It is also unique for the fact that the race changes drastically from start to finish. It starts around 6:20 PM and the track is bathed in sunlight for the first third of the race. The second third happens at dusk, and the final third under the lights.
