Coca-Cola 600
Updated: Wikipedia source
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 a Sunday during Memorial Day weekend. The first race, held in 1960, was also the first one held at Charlotte Motor Speedway. 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 6:20 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 usually held on the last weekend of May and is known as one of the largest weekends in auto racing, as the NASCAR race occurs on the same Sunday after the Monaco Grand Prix (Formula One) and the Indianapolis 500 (IndyCar Series). Ross Chastain is the defending champion of the Coca-Cola 600.
