Sunday, July 20, 1986 – Tim Richmond, accustomed to winning by somewhat more comfortable margins, came out on top in a last-lap drag race with Ricky Rudd to the finish line to win the Summer 500 at Pocono (Pa.) Raceway. Richmond, driving the No. 25 Chevrolet for Hendrick Motorsports, passed teammate Geoff Bodine for the lead to start the last lap, but the race out of Turn 3 saw Rudd come charging to the inside of the two frontrunners. Richmond’s margin of victory over Rudd was 0.05 second.
• The victory was the third in four races for Richmond, who became the third driver in five seasons to sweep both races at the 2.5-mile track.
• The race was cut from 200 to 150 laps due to poor visibility resulting from fog in the area. The start of the race had been delayed approximately 90 minutes because of weather issues.
• Richmond won despite sustaining heavy damage to his vehicle during a wreck; he lost nearly two laps while repairs were being made.
• Neil Bonnett, driver of the No. 12 Chevrolet fielded by Junior Johnson, was transported to a local hospital after his involvement in a five-car incident on lap 126. He was treated for a broken collarbone and rib.
