Generally, races are single events of at least 300 kilometers, though in 2011, the minimum distance was reduced to 250 km due to the 2011 Tōhoku earthquake and tsunami. Furthermore, the 2016 Kumamoto earthquakes forced the GTA to cancel its Autopolis round, substituting the race with Super GT's sole instance of a double-header event, comprising two 250 km races held at Motegi.
