The Bend Motorsport Park will host the opening round of Enduro Cup in the 2020 Supercars season.
Sam Shahin, the man behind the new $130 million park hosting The Bend SuperSprint this weekend, confirmed Tailem Bend would become an endurance event next year.
In the Supercars season, there are three endurance rounds which are longer races and worth double the points - the Bathurst 1000, Sandown 500 and Gold Coast 600.
With the Supercars Commission meeting this week to discuss the 2020 calendar, it is believed Sandown will become a SuperSprint event.
Tailem Bend will likely move into the September slot and become the warm-up event for Bathurst.
