The Cook Out 400 is an annual NASCAR Cup Series stock car race held at the 0.526-mile (0.847 km) Martinsville Speedway in Ridgeway, Virginia. It is the first of two Cup Series races at the track, the other one being the Xfinity 500 in the NASCAR playoffs.

The race was previously 500 laps in length before it was shortened to 400 laps starting in 2022.

Unlike other races which the winner receives a trophy, the winner of this race and other NASCAR races at Martinsville receives a grandfather clock, which has been a tradition since 1964.^[2][3]

The race had no name from 1950 to 1955, before taking the name Virginia 500 in 1956.

Goody's Powder, which was the title sponsor of the spring Martinsville Cup Series race from 1996 to 2000 and the fall Martinsville Cup Series race from 1983 to 1995, returned as the title sponsor of the spring race in 2007 to promote their new orange-flavored brand, Cool Orange, with the race title being Goody's Cool Orange 500. During this time, this race was the sixth race of the season and the first race where the current season's owner point standings were used to determine which cars were "go-or-go-homers" and needed to qualify into the race. (For the first five races, it was the previous season's owner point standings used to determine which cars were locked in the race.)

From 2008 to 2012, the fall Cup Series race at Martinsville was sponsored Tums, which was owned by the same parent company (British pharmaceutical conglomerate GSK plc) as Goody's. In 2013, they reduced their title sponsorship to only the fall race with Goody's replacing Tums as the brand that was advertised in the race sponsorship. Legendary NASCAR and Richard Petty sponsor STP became the title sponsor of the spring race starting in 2013 and remained through 2019.

In 2020, Blue-Emu took over naming rights for the race as part of a multi-year deal with NASCAR.^[4]

In 2022, the race was shortened to 400 laps.

In 2023, The NOCO Company, which makes car parts such as batteries, battery chargers and jumper cables, replaced Blue-Emu as the title sponsor of the race.^[5]

In 2024, the race had another new title sponsor, Cook Out.^[1]

• 1953: Herb Thomas was originally declared the winner, but a recheck showed that he had been credited with an extra lap.
• 1971: Controversy dogged Richard Petty's win as he lost his gas cap (dry-break fuel couplers were not mandated until 1974) during the race but was not black-flagged; there had been incidents of drivers flagged to get gas caps under green.

Of Shepherd's four career victories, this was the only one at a track other than Atlanta.
• 1982: After nearly a dozen second-place finishes, Harry Gant pulled down his first win.

• 1999: John Andretti lost a lap after being tagged by Ward Burton; he made up the lap and ran down Jeff Burton; in the final ten laps he and Burton raced nose to nose for several laps before Andretti rallied to the win, his first for Petty Enterprises, the 200th short track win for the team, and the first for the team since 1997.

• 2010: Denny Hamlin stormed four-abreast through traffic on a late restart to steal the win.
• 2012: Ryan Newman stormed to the checkered flag because of the wreck that happened before. Clint Bowyer hit both Jimmie Johnson and Jeff Gordon during the first attempt. Newman held off A. J. Allmendinger on the second attempt to win the Goody's Fast Relief 500.
• 2014: Kurt Busch posted his first win with Stewart-Haas Racing after passing Jimmie Johnson with eleven laps to go. The win was Busch's first in two seasons following his firing from Penske Racing and numerous confrontations with media. The race lead changed 33 times, a track record, breaking the 31 sets in Kevin Harvick's 2011 win.
