This year's race sees the Starworks Motorsport team on pole position, with a lineup that features endurance racing legend Allan McNish. Last year's winner, Chip Ganassi Racing were unable to qualify one of their cars and thus start from the back of the grid. With 24 hours and a 5.73 kilometre course in front of them, it's all to play for as the 50th anniversary of the race gets underway. Oh, and look out for bonus Patrick Dempsey somewhere in the field.
