The 1991 Champion Spark Plug 500 was the 13th stock car race of the 1991 NASCAR Winston Cup Series season and the tenth iteration of the event. The race was held on Sunday, June 14, 1991, in Long Pond, Pennsylvania, at Pocono Raceway, a 2.5 miles (4.0 km) triangular permanent course. The race took the scheduled 200 laps to complete. In the final laps of the race, owner-driver Darrell Waltrip would mount a late-race charge for the lead, passing with 18 laps to go in the race to take his 81st career NASCAR Winston Cup Series victory and his second and final victory of the season. To fill out the top three, Richard Childress Racing driver Dale Earnhardt and Roush Racing driver Mark Martin would finish second and third, respectively. Background The race was held at Pocono International Raceway, which is a three-turn superspeedway located in Long Pond, Pennsylvania. The track hosts two annual NASCAR Sprint Cup Series races, as well as one Xfinity Series and Camping World Truck Series event. Until 2019, the track also hosted an IndyCar Series race. Pocono International Raceway is one of a very few NASCAR tracks not owned by either Speedway Motorsports, Inc. or International Speedway Corporation. It is operated by the Igdalsky siblings Brandon, Nicholas, and sister Ashley, and cousins Joseph IV and Chase Mattioli, all of whom are third-generation members of the family-owned Mattco Inc, started by Joseph II and Rose Mattioli. Outside of the NASCAR races, the track is used throughout the year by the Sports Car Club of America (SCCA) and motorcycle clubs as well as racing schools and an IndyCar race. The triangular oval also has three separate infield sections of racetrack – North Course, East Course and South Course. Each of these infield sections use a separate portion of the tri-oval to complete the track. During regular non-race weekends, multiple clubs can use the track by running on different infield sections. Also some of the infield sections can be run in either direction, or multiple infield sections can be put together – such as running the North Course and the South Course and using the tri-oval to connect the two.
