Previously, most race weekends have featured a practice session limited to 20-25 minutes with Cup teams separated into two groups based on a performance metric formula. James Gilbert / Getty ImagesJuly 18, 2026 2:33 pm EDT Updated NORTH WILKESBORO, N.C. — NASCAR is expected to double how much practice time Cup Series teams get most weeks, multiple sources within race teams told The Athletic. They were granted anonymity to discuss the change that has not been publicized yet.With an increasing chorus of drivers and fans calling for additional track time, NASCAR officials will change the practice format from two groups of 25 minutes each to one 50-minute session involving all cars. Under the proposed changes, teams would also be allotted two tire sets so they can then better make multiple runs during the session. The additional practice time is expected to go into effect beginning with next month’s race weekend at New Hampshire and remain in place for every race but two — Daytona and Talladega. Those are superspeedway tracks and will continue not to have any practice. Homestead’s practice schedule will also be unchanged because it already has a 50-minute practice scheduled due to being the site of the championship finale.
