The Bathurst 1000 (currently branded as the Supercheap Auto Bathurst 1000 for sponsorship reasons) is a 1,000 km touring car race held annually on the Mount Panorama Circuit in Bathurst, New South Wales, Australia. It is currently run as a championship event for Supercars.
The bathurst 1000 will end in 2020
The article says nothing about when the race will finish, so it can not be ruled out that the races final year will be 2020. I think the system has a hard time understanding the future.
