Four races have been given new green flag times for the 2020 NTT IndyCar Series season.

Three of the four will shift to a later start than in 2019, the most notable being Iowa, which will more fully embrace its night race status with a green flag at 9pm ET (8pm local). This year’s race started at 7:15pm Eastern. St Petersburg and COTA, meanwhile, will shift from early afternoon to mid-afternoon. St Pete will have a 3:30pm green flag for its 10th anniversary event, which will be televised on NBC Sports Network – one hour and 50 minutes later than this year’s race. COTA will have a similar change, going from a 1:43pm ET green flag to 4:10pm ET (3:10pm local) for 2020.

The only race that will start earlier than its 2019 counterpart is Mid-Ohio, which had a 4:05pm ET start this year, and will change to 12:45pm ET.

Meanwhile, IndyCar’s decade-plus absence from Richmond will be broken with a night race that will be given the green flag at 8:15pm ET on Saturday, June 27.
