The 2010 NASCAR Sprint Showdown and Sprint All-Star Race was the 26th running of NASCAR's special non-points race involving winners of the 2009 and 2010 NASCAR Sprint Cup Series races through the 2010 Autism Speaks 400 as well as Sprint All-Star Race 2000–2009 winners, when the event was known as "The Winston" and the "Nextel All-Star Challenge", and past Sprint Cup champions from the decade covering 2000 to 2009, including the "Winston Cup" (2000–2003) and "Nextel Cup" (2004–2007) eras. The event was run at the Charlotte Motor Speedway in the Charlotte, North Carolina suburb of Concord on May 22, 2010. Speed provided television coverage in the US while MRN (over-the-air/terrestrial) and Sirius XM Radio (satellite) held radio rights. Race format The format of the race was follows: One fifty-lap segment with a mandatory four-tire green flag pit stop at or around Lap 25; Two twenty-lap segments with a ten-minute break following Segment Three; A ten-lap green flag segment. Pits were open following the end of the first two segments, where drivers could have opted to take a pit stop, but could have sacrificed their position on the track should they chose to do so. After the first pace lap following the break, teams were required to take a four-tire stop. The order they come out determined the starting order for the last segment. The qualifying session for eligible drivers was to have consisted of three laps instead of the standard two, including a pit stop after either of the first two laps, slowing to the speed limit of 45 mph entering pit road, but going full throttle as they exit. However, a rainstorm the night before (May 21) cancelled the event, and the first 19 positions were chosen by the luck of the draw for the cancelled qualifying; as a result, Kurt Busch and Joey Logano made up the front row.
