What is the track length of Martinsville Speedway?

Martinsville Speedway’s track length is 0.526 miles.

The short oval sits in Ridgeway, Virginia, near the city of Martinsville. Its compact shape and tight four corners earned it the nickname “The Paperclip,” and the circuit is the shortest track on the current NASCAR Cup Series schedule.

Martinsville opened in 1947 under Henry Clay Earles and hosted its first NASCAR Cup race in 1949. It began as a dirt track, was paved with asphalt in 1955, and later received concrete in the lower lanes of its turns. The mixed surface remains one of the venue’s distinctive features.

The 0.526-mile measurement dates to 1969, when NASCAR changed its track-length measurement system. Older references may describe Martinsville as a half-mile track, which explains why 0.500 miles can appear in historical material. Modern race listings use 0.526 miles, or roughly 0.847 kilometers.
