New Hampshire International Speedway is a 1.058-mile (1.703 km) oval speedway located in Loudon, New Hampshire which has hosted NASCAR racing annually since the early 1990s, as well as an IndyCar weekend and the oldest motorcycle race in North America, the Loudon Classic. Nicknamed "The Magic Mile", the speedway is often converted into a 1.6-mile (2.6 km) road course, which includes much of the oval. The track was originally the site of Bryar Motorsports Park before being purchased and redeveloped by Bob Bahre. The track is currently one of eight major NASCAR tracks owned and operated by Speedway Motorsports.

Qualifying was split into two rounds. The first round was held on Friday, July 7, at 4:00 PM EST. Each driver would have one lap to set a time. During the first round, the top 20 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, July 8, at 11:00 AM EST. As with the first round, each driver would have one lap to set a time. For this specific race, positions 21-38 would be decided on time,^[3] and depending on who needed it, a select amount of positions were given to cars who had not otherwise qualified but were high enough in owner's points.

Mark Martin, driving for Roush Racing, would win the pole, setting a time of 29.568 and an average speed of 128.815 miles per hour (207.308 km/h).^[4]

Eric Smith was the only driver to fail to qualify.
