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. IndyCar formed the IndyCar iRacing Challenge, with its drivers racing against one another on the iRacing racing simulation game. On 26 March, IndyCar announced that it would postpone the two Indianapolis races to later in the season—moving the GMR Grand Prix to the Fourth of July as support for the NASCAR Cup Series' Brickyard 400 (and creating a rare NASCAR/IndyCar double-header with the Xfinity Series' Pennzoil 150), and the 500 to 23 August—marking the first time in history that it has not been held in May. Therefore, the season was to tentatively begin with the Detroit Grand Prix. The Grand Prix of St. Petersburg was reinstated as the planned season finale, with a date to be determined. On 6 April, IndyCar announced that the Detroit Grand Prix had been canceled. To make up for other canceled races, it was announced that a third race at Indianapolis (the IndyCar Harvest GP, a second race on the track's road course) would be added to the schedule in October, and that the Iowa 300 and Monterey Grand Prix would become twin race weekends with two points-paying races each. On 7 May, IndyCar officially announced that the season would begin 6 June with the Genesys 300 at Texas Motor Speedway, with races held with limited spectators (only those that owned units in the Turn 2 Lone Star Tower were allowed to attend the race, a practice that began at the NASCAR weekend in Charlotte that is also owned by Sonic Automotive) and with enhanced safety protocols until further notice. To accommodate same-day qualifying and practice, the race was shortened from its usual 248-lap (600 kilometer) distance to 200 laps (300 miles). Although circuit president Eddie Gossage originally insisted that he would not allow the race to be held unless as support for a NASCAR event (the postponed March NASCAR tripleheader was rescheduled for July), he later came to terms with new series owner Roger Penske. The NASCAR Gander RV & Outdoors Truck Series race scheduled after the originally scheduled Friday qualifying of the INDYCAR weekend was postponed to October 25, becoming part of
