MOORESVILLE, N.C. (March 25, 2025) – Wrestling a racecar for 400 laps around Martinsville (Va.) Speedway necessitates a strong upper-body and powerful legs, connected with a tight core. The flat, paperclip-shaped .526-mile oval makes for a physical race where drivers have to pull their steering wheel hard to the left 800 times while stabbing their brake pedal at the end of each, 800-foot-long straightaway. Whether one’s car is lightning quick or could use a jolt of lightning, Martinsville pushes the boundaries of human performance as much as a car’s mechanical limits.
