<Tr> <Th> Turns </Th> <Td> </Td> </Tr> <P> The Advance Auto Parts Clash is an annual invitation - only Monster Energy NASCAR Cup Series exhibition event held at Daytona International Speedway in February, the weekend before the Daytona 500 . It is the first competitive event of the season and serves as a kickoff event for the NASCAR portion of Speedweeks . </P> <P> The event was originally known as the Busch Clash, and consisted of a 20 - lap / 50 - mile, "all - out sprint" for the previous season's pole position winners (considered the de facto "fastest drivers on the circuit"). In its current format it is made up of two segments, a 25 lap start that then culminates in a 50 lap final segment . </P> <P> Like the All - Star Race held at Charlotte, the race awards no championship points but instead offers a large cash purse--circumstances which are supposed to encourage an all - out driving style not seen in regular - season races . </P>
