The NASCAR Cup and Xfinity Series will be on track for roughly eight consecutive hours Friday at Bristol Motor Speedway.

Xfinity will begin a 55-minute practice at 2 p.m. ET, followed by qualifying for a 300-lap race on the 0.533-mile oval that will open at the series' 2025 playoffs at 7:30 p.m. Regular-season champion Connor Zilisch will bring a four-race winning streak into Bristol.

The Cup Series will begin an hourlong practice session at 4:30 p.m., followed by qualifying for a 500-lap race Saturday night. For the first time in four races at Bristol, there will be a new right-side tire with a softer compound designed to produce more wear on the track's concrete.

Alex Bowman, who is among the four drivers below the cutline entering Saturday's first-round finale, has won the past two pole positions at Bristol.
