The race took the scheduled 300 laps to complete. At race's end, Tony Stewart of Joe Gibbs Racing would dominate the race to take his 22nd career NASCAR Nextel Cup Series win and his third of the season.

The layout of New Hampshire International Raceway, the venue where the race was held.

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.

The first one-hour practice session would take place on Friday, July 15, at 12:10 PM EST. Mark Martin of Roush Racing would set the fastest time in the session, with a lap of 29.418 and an average speed of 129.472 miles per hour (208.365 km/h).

The second and final one-hour practice session would take place on Friday, July 15, at 3:50 PM EST. Ryan Newman of Penske Racing would set the fastest time in the session, with a lap of 29.086 and an average speed of 130.950 miles per hour (210.744 km/h).

Qualifying would take place on Saturday, July 16, at 12:10 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.

Brian Vickers of Hendrick Motorsports would win the pole, setting a time of 29.225 and an average speed of 130.327 miles per hour (209.741 km/h).

Carl Long of McGlynn Racing would crash during his second lap. While he had crashed, he had set a lap time fast enough in the first lap to get him into the race, and therefore was able to still compete, albeit at the rear due to switching to a backup car.

Four drivers would fail to qualify: Joey McCarthy, Derrike Cope, Wayne Peterson, and Hermie Sadler.
