The Can-Am Duel, formerly known as the Twin 125s, is a Monster Energy NASCAR Cup Series preliminary event to the Daytona 500 held annually in February at Daytona International Speedway.
 It consists of two 150 mi races, which both serve as a qualifying race for the Daytona 500.
 The finishing order in the two 150 mi races, held on the Thursday before the Daytona 500, determine the starting lineup for the Daytona 500 held on race day.
The 1987 Daytona 500, the 29th running of the event, was held February 15 at Daytona International Speedway, in Daytona Beach, Florida.
 Bill Elliott won the pole and the race.
The 2002 Daytona 500, the 44th running of the event, was held on February 17 at Daytona International Speedway in Daytona Beach, Florida as the first of 36 races of the 2002 Winston Cup Season.
 Rookie Jimmie Johnson, driving the No. 48 Chevrolet for Hendrick Motorsports, won the pole with fellow Daytona 500 rookie Kevin Harvick qualifying second, making this the first time the field would be led by two first-time Daytona 500 participants.
 Ward Burton, driving the No.22 Dodge for Bill Davis Racing, won the race.
 This race was the last for long-time veteran driver Dave Marcis.
The 2006 Daytona 500, the 48th running of the event, was the first race in the 2006 NASCAR Nextel Cup season.
 It was held on February 19, 2006 at Daytona International Speedway in Daytona Beach, Florida.
 Jimmie Johnson won the race in a green-white-checker finish.
 It was the second Daytona 500 in a row to go longer than 200 laps and 500 miles ; this race, like the previous Daytona 500, had a total distance of 203 laps and 507.5 miles .
 This was also the first Daytona 500 to end after dark, ending even later than the 2005 race, in which the checkered flag had waved just a few moments after sunset.
The 2011 Daytona 500, the 53rd running of the event, was held on February 20, 2011 at Daytona International Speedway in Daytona Beach, Florida as the first race of the 2011 NASCAR Sprint Cup season.
 Trevor Bayne, driving for Wood Brothers Racing, won the race becoming the youngest Daytona 500 winner.
 Carl Edwards finished second, while David Gilliland, Bobby Labonte, and Kurt Busch rounded out the Top 5.
 Bayne had taken the lead shortly before the final restart and maintained it to win his first Cup Series race and Wood Brothers' fifth Daytona 500.
Daytona 500 pole position winners for the Monster Energy NASCAR Cup Series's Daytona 500 are rewarded with being the driver to lead the field across the start line at the beginning of the 200-lap 500 mi race.
 Pole qualifying for the Daytona 500 is held one weekend before the race at the Daytona International Speedway.
 The driver to complete the fastest single lap in the final of three rounds in the knockout qualifying session around the 2.5 mi high-banked tri-oval superspeedway earns the pole position.
 The first Daytona 500 was held in 1959 and in 1982, it became the opening event for the NASCAR Cup season.
 The term "pole position" was originally coined in the American horse racing industry, and indicated the position of the starter being next to the "poles", which established the boundaries of the course.
 The two drivers who complete a lap with the fastest time are awarded the first and second starting positions for the Daytona 500.
 An additional 33 to 35 entrants are determined by a combination of the results of two qualifying races and the position of the team in the previous season's point rankings.
 The remainder of the 43 car field consists of drivers who meet certain qualifications, such as qualifying speed or being one of the previous NASCAR champions.
The 1998 Daytona 500, the 40th running of the event, was held on February 15 at Daytona International Speedway in Daytona Beach, Florida as the first race of the 1998 NASCAR Winston Cup season.
 It was memorable in that it marked Dale Earnhardt's only Daytona 500 victory after 19 previous attempts and many heartbreaking finishes.
 Not only was it Earnhardt's 20th 500 start, but also CBS's 20th consecutive live broadcast of the Daytona 500.
 Also, his long-awaited Daytona 500 win snapped a 59-race winless streak dating back to Atlanta Motor Speedway in March 1996.
The 1985 Daytona 500, the 27th running of the event, was held on February 17, 1985, at Daytona International Speedway, in Daytona Beach, Florida.
 Bill Elliott won the pole at a then-record speed of 205.114 mph.
 After a mediocre run in the Busch Clash, Elliott nearly lapped the field in his 125-mile qualifying race, then thoroughly dominated the Daytona 500, leading 136 of the 200 laps in his #9 Coors/Melling Ford Thunderbird.
 The race restarted on the last lap after a Neil Bonnett spin out with less than four laps to go; Bonnett got out of his car and was credited for a 10th-place finish.
 The race saw a number of engine problems, which knocked many of the contenders, including former Daytona 500 winners David Pearson, AJ Foyt, Benny Parsons, Bobby Allison, and two-time defending race winner Cale Yarborough, who was trying to win his third straight Daytona 500 victory.
The Daytona 500 Experience, formerly known as Daytona USA, was an interactive motorsports attraction and museum located at Daytona International Speedway in Daytona Beach, Florida.
 Intrinsically linked to the Daytona 500, the museum primarily focused on exhibits related to NASCAR.
 The attraction also included exhibits related to the Daytona 200 motorcycle race, the 24 Hours of Daytona, as well as the Daytona Beach & Road Course.
William Clyde "Bill" Elliott (born October 8, 1955), also known as Wild Bill, Awesome Bill from Dawsonville, or Million Dollar Bill, is a retired NASCAR driver.
 He won the 1988 Winston Cup Championship and has garnered 44 wins in that series, including two Daytona 500 victories in 1985 and 1987 and a record four consecutive wins at Michigan International Speedway between 1985 and 1986.
 He holds the track record for fastest qualifying speed at Talladega at 212.809 mph and Daytona International Speedway at 210.364 mph , both of which were set in 1987; the mark at Talladega has since been the fastest speed for any NASCAR race ever.
