SciAps 300

The SciAps 300 is a NASCAR Xfinity Series race held at Bristol Motor Speedway, known for its 300-lap, 0.533-mile short track racing. It evolved from a 150-lap event in 1982 and extended to 300 laps in 2006. The race adopted stage racing in 2017 after experimenting with heat races in 2016. It was not held from 2021 to 2024 due to the track’s temporary dirt configuration but returned to the concrete surface and schedule in 2025.
