The 2008 Tums QuikPak 500 was a Sprint Cup Series event held at Martinsville Speedway on October 19, 2008. Jimmie Johnson won a race that was his to lose and suddenly found the championship his to lose as well. Johnson held off teammate Dale Earnhardt, Jr. on a green-white-checkered to take a 149-point championship lead on Greg Biffle (12th) with just four races to go in the Chase. Former lead Johnson chaser Jeff Burton struggled to 17th following a pit-road penalty, and he sat in third 152 markers back. Stats
