NASCAR Cup Series

The NASCAR Cup Series is the top level of the sport and is the main event of the weekend, usually held on Sunday. It features the biggest teams and most well-known drivers in NASCAR, competing in the longest and most prestigious race of the weekend. Cup races typically cover 300 to 500 miles, depending on the track.

O'Reilly Auto Parts Series

The O'Reilly Auto Parts Series is NASCAR’s second-tier championship and usually takes place on Saturday. It’s designed to develop up-and-coming talent, though some experienced Cup drivers may also compete. Xfinity races are shorter than Cup races but still deliver exciting, competitive action.
