The Coca-Cola 600 is an annual 600-mile NASCAR Sprint 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. It is also unique for the fact that the race changes drastically from start to finish. It starts around 6:20 PM in the afternoon in full sunlight, and the track is bathed in sunlight for the first third of the race. The second third happens at dusk, and the race is running under the lights by the end.
