World 600

The Coca-Cola 600, originally the World 600, is an annual 600-mile (970 km) NASCAR Cup Series points race held at the Charlotte Motor Speedway in Concord, North Carolina, on the fourth or last Sunday of May and during Memorial Day weekend. It is the longest race on NASCAR's schedule. It is unique for having track conditions that change throughout the race due to the race having a day to night transition (if the race occurs on schedule with no delays or postponements). The race starts around 6 p.m. when the track is bathed in sunlight for about the first third of the race. Roughly the second third happens at dusk, and about the final third of the race occurs at night under the lights. The race is run later on the same day as the Indianapolis 500 of the IndyCar Series, with multiple drivers having performed or attempted Double Duty, competing in both races. No driver has ever won both races, either on the same day or across their career. The NASCAR event is held on the last weekend of May (also known as "the greatest day/weekend in motorsports" due to it being one of the largest weekends in auto racing). The NASCAR race occurs last on the same Sunday after Formula One's Canadian Gran
