The NASCAR Cup Series heads to World Wide Technology Raceway at Gateway Sunday afternoon for the Enjoy Illinois 300. The race will feature 240 laps around the 1.25-mile oval, with the stages ending on laps 45, 140, and 240. WWTR is one of the more unique tracks on the schedule because Turns 1 and 2 are tighter than Turns 3 and 4, forcing teams to compromise on the setup and putting a premium on braking stability, center rotation, and rear grip on corner exit.

The NASCAR O’Reilly Auto Parts Series heads to World Wide Technology Raceway at Gateway Saturday night for the Nu Way 225 Powered by Bobcat and Sauced by Blues Hog. The race will feature 180 laps around the 1.25-mile oval, with the stages ending on laps 45, 90, and 180. WWTR is one of the more unique tracks on the schedule because the two ends of the track are completely different and require drivers to use a lot of brake while still maintaining rear grip on corner exit.

The NASCAR Cup Series heads to Darlington Raceway this weekend for one of the biggest races of the season in the Cook Out Southern 500. The 500-mile race will be 367 laps around the historic 1.366-mile oval and will also be the first race of The Chase for the Cup. That gives us a long race with plenty of dominator points available and even more pressure on the drivers trying to start their championship run with a strong finish.

The NASCAR O’Reilly Auto Parts Series heads to Darlington Raceway Saturday night for the Fleetio 200. The race will feature 147 laps around the 1.366-mile oval, with the stages ending on laps 45, 90, and 147. Darlington is one of the most difficult tracks on the schedule because of its narrow racing surface, unique egg-shaped layout, and extreme tire wear throughout a green-flag run.

The NASCAR Cup Series heads back to Daytona International Speedway Saturday night for the Coke Zero Sugar 400 and the final race of the regular season.

Daytona is one of the most unpredictable races on the schedule as drivers will spend most of the night racing in large packs where one mistake can take out a significant portion of the field.
