Daytona International Speedway is a race track in Daytona Beach, Florida that is one of six superspeedways to hold NASCAR races, the others being Auto Club Speedway, Indianapolis Motor Speedway, Michigan International Speedway, Pocono Raceway and Talladega Superspeedway.[1] The standard track at Daytona is a four-turn superspeedway that is 2.5 miles (4.0 km) long. The track also features two other layouts that utilize portions of the primary high speed tri-oval, such as a 3.56-mile (5.73 km) sports car course and a 2.95-mile (4.75 km) motorcycle course.[2] The track's 180-acre (73 ha) infield includes the 29-acre (12 ha) Lake Lloyd, which has hosted powerboat racing. The speedway is owned and operated by International Speedway Corporation.


The race is famous for one of the longest green flag runs ever. There were only two brief yellows in the first half for a total of ten laps. The final 81 laps (the entire second half) were run under green, setting up a finish where fuel strategy was going to be key to deciding the winner. Rookie Greg Biffle won the event for his first Cup Series victory. His win was an upset after Bobby Labonte ran out of gas in the final laps, likewise, Kevin Harvick led the most laps at 54, but also failed to win.
