The race was originally scheduled to be run for 24 laps, but was initially shortened to 16 laps amid bad weather conditions. After heavier rainfall, race direction red-flagged the race after 8 full laps and decided not to restart the race. As a consequence, half points were awarded after failing to complete 2/3 of the race distance.^[7]
