Past winners

 * 2010: The race extended due to a NASCAR Overtime finish.
 * 2019: Race postponed from Saturday night to Sunday afternoon due to rain; Ross Chastain had originally won the race, but his truck failed post-race tech. With NASCAR's new tech policy that if the winning vehicle fails, the vehicle will be disqualified and whoever finished 2nd or is the highest finishing driver whose vehicle passes moves up. Brett Moffitt originally finished 2nd in the race, but due to Chastain's truck failing, and Moffitt passing post-race tech, Moffitt wound up winning the race despite the fact he never led a lap the whole race. This marked the first time since an Xfinity race in 1995 that a driver was disqualified due to post-race tech failure, and stripped of the win.
 * 2020: Race canceled and moved to the Daytona Road Course due to the COVID-19 pandemic.
