Martinsville Speedway is an NASCAR-owned stock car racing track located in Henry County, in Ridgeway, Virginia, just to the south of Martinsville. At 0.526 miles (0.847 km) in length, it is the shortest track in the NASCAR Cup Series. The track was also one of the first paved oval tracks in NASCAR, being built in 1947 by H. Clay Earles. It is also the only remaining race track that has been on the NASCAR circuit from its beginning in 1948.

Qualifying was split into two rounds. The first round was held on Friday, September 29, at 3:00 PM EST. Each driver would have two laps to set a fastest time; the fastest of the two would count as their official qualifying lap. During the first round, the top 25 drivers in the round would be guaranteed a starting spot in the race. If a driver was not able to guarantee a spot in the first round, they had the option to scrub their time from the first round and try and run a faster lap time in a second round qualifying run, held on Saturday, September 30, at 11:15 AM EST. As with the first round, each driver would have two laps to set a fastest time; the fastest of the two would count as their official qualifying lap.^[3] Positions 26-36 would be decided on time, while positions 37-43 would be based on provisionals. Six spots are awarded by the use of provisionals based on owner's points. The seventh is awarded to a past champion who has not otherwise qualified for the race. If no past champion needs the provisional, the next team in the owner points will be awarded a provisional.^[7]

Tony Stewart of Joe Gibbs Racing would win the pole, setting a time of 19.855 and an average speed of 95.371 miles per hour (153.485 km/h).^[8]

Five drivers would fail to qualify: Scott Pruett, Steve Grissom, Carl Long, Dave Marcis, and Rich Bickle.
