On March 26, the IndyCar Series announced that the 2020 Indianapolis 500 would be held on August 24, 2020—marking the first time since the race resumed in 1946, after the conclusion of World War II, that it was not held on Memorial Day weekend. Indianapolis Motor Speedway's road course race, the GMR Grand Prix, was held on July 4, 2020, during the NASCAR Cup Series' Brickyard 400 race weekend, as part of a double-header with the NASCAR Xfinity Series' Pennzoil 150, all of them held behind closed doors. IndyCar had delayed the start of the 2020 season due to the pandemic.
