Martinsville Speedway is an International Speedway Corporation-owned NASCAR stock car racing track located in Martinsville, Virginia. At 0.526 miles in length, it is the shortest track in the NASCAR Nextel Cup Series. The track was also one of the first paved "superspeedways" in NASCAR, being built in 1947. The track is shaped like a huge paper clip and is banked 12° in the turns. Of note, winners of the spring Martinsville race receive a grandfather clock as a trophy instead of a regular trophy, a tip of the cap to the fame of the Martinsville furniture industry.
