It was the 9th race in the 2020 IMSA WeatherTech Sportscar Championship, and the 3rd race of the 2020 Michelin Endurance Cup, and was run at Road Atlanta in Braselton, Georgia.

Background 

Then International Motor Sports Association's (IMSA) president Scott Atherton confirmed the race was part of the schedule for the 2020 IMSA SportsCar Championship (IMSA SCC) in August 2019. It was the seventh consecutive year it was part of the IMSA SCC, and the 23rd Petit Le Mans. The 2020 Petit Le Mans was the ninth of eleven sports car races of 2020 by IMSA, and the third of four races of the Michelin Endurance Cup (MEC). The race took place at the 12-turn,  Road Atlanta in Braselton, Georgia. The event was one of the first postponed by IMSA as a result of the emerging COVID-19 pandemic, with the organization citing CDC regulations on public gatherings as the official cause of postponement. The race was rescheduled from running on October 10, 2020, to October 17, 2020. Due to the 12 Hours of Sebring getting postponed, Petit Le Mans would not be the season finale for the first time in the IMSA WeatherTech SportsCar Championship.
