The Cook Out 400 at Richmond Raceway was completely sold out on Saturday, as fans flocked to witness the high-speed action that the three-quarter-mile oval delivers. The race turned out to be a huge hit as William Byron clinched the 2025 NASCAR Cup Series Regular Season Championship, while Austin Dillon secured his sixth career victory.

There are just two races left in the 2025 regular season. Thanks to Shane van Gisbergen winning for an impressive fourth time on a road course this season, taking home the checkered flag at Watkins Glen, there will be a driver that will qualify for the postseason without a win.

NASCAR's Cup Series racing returns to Richmond Raceway on August 16. Enjoy an action-packed Saturday night under the lights. The Cook Out 400 marks the 137th Cup race hosted by Richmond Raceway in the history of the series. NASCAR will only visit Richmond Raceway once in 2025.
