2025 Cook Out Southern 500

Background , where the race was held. Darlington Raceway is a race track built for NASCAR racing located near Darlington, South Carolina. It is nicknamed "The Lady in Black" and "The Track Too Tough to Tame" by many NASCAR fans and drivers and advertised as "A NASCAR Tradition." It is of a unique, somewhat egg-shaped design, an oval with the ends of very different configurations, a condition which supposedly arose from the proximity of one end of the track to a minnow pond the owner refused to relocate. This situation makes it very challenging for the crews to set up their cars' handling in a way that is effective at both ends.
