In wake of the Rudy Gobert and NBA situation, the IndyCar Series initially announced on 12 March that it would hold the Grand Prix of St. Petersburg — the opening race of the 2020 season — behind closed doors.[61] On 13 March in respect of the NBA suspension, the series announced that it would cancel all races through at least the end of April, including St. Petersburg, Alabama, Long Beach, and Austin. IndyCar intended to begin the season with the traditional "Month of May" races at Indianapolis Motor Speedway, including the GMR Grand Prix (held on IMS's road course configuration), and the 104th running of the Indianapolis 500 on its traditional Memorial Day Sunday date.[62] IndyCar formed the IndyCar iRacing Challenge, with its drivers racing against one another on the iRacing racing simulation game.[63]
