Martinsville Speedway is 0.526 miles long, or about 0.847 kilometers —it’s NASCAR’s shortest track. It also sits on roughly 200 acres , so the facility is much larger than the racing surface itself.

Track size

  • Racing surface length: 0.526 miles.
  • Approximate track facility size: 200 acres.
  • Shape: a tight, flat “paperclip” oval with two long straightaways and very tight turns.

Why it feels big

Even though the lap is short, Martinsville feels intense because the track is narrow, the corners are tight, and passing is difficult. That compact layout is a big part of why it’s such a famous short track in NASCAR.

One-line answer

If you mean the actual racing track, it’s just over half a mile long.
