How many feet long is an eighth-mile drag strip?

An eighth-mile drag strip is 660 feet long.

The distance is exactly one-eighth of a traditional quarter-mile drag race: 1,320 feet divided by eight equals 165 feet per eighth, and the commonly used eighth-mile distance is 660 feet, or half of 1,320 feet. In everyday drag-racing terminology, “eighth-mile” means 660 feet.

Short tracks became especially popular for street-oriented events, bracket racing, and venues where a full quarter-mile was impractical. Drivers still record elapsed time and trap speed, but the shorter course changes the balance between launch, traction, gearing, and top-end power.

A common mix-up is confusing 660 feet with 1,000 feet. The latter is the modern standard race distance for Top Fuel and Funny Car competition in major sanctioning contexts, while 1,320 feet remains the traditional quarter-mile. Track layouts may include extra shutdown area beyond the measured racing distance.
