135: The greatest number of laps ever run in NASCAR Sprint All-Star Race. It happened three times, in 1987, 1988 and 1989, when the all-star race was contested in segments of 75, 50 and 10 laps, with only green-flag laps counting in the final segment. The 1987 race also was notable for 1) the return to Charlotte as its permanent home after a one-shot visit to Atlanta; 2) the move of the all-star race to a new date, the weekend before the Coca-Cola 600; and 3) the establishment of a last-chance qualifier for the main event, now known as the Sprint Showdown. In 1990, the length of the race was trimmed drastically, to 70 laps, run in segments of 50 and 20 laps. This year, drivers will run a total of 90 laps, contested in segments of 20, 20, 20, 20 and 10 laps.
