DAYTONA BEACH, Fla. – The six-race IMSA Prototype Challenge season, which opened with a three-hour race at Daytona Int’l Speedway on Jan. 4, will resume on the weekend of July 17-18 at Sebring Int’l Raceway as part of a revised calendar unveiled Friday by IMSA officials.
The Sebring event will run as a companion to IMSA WeatherTech SportsCar Championship and IMSA Michelin Pilot Challenge races, which is the case for all six of the series’ race weekends in 2020. The IMSA Prototype Challenge season will reach its halfway point at Road America on the weekend of July 31-Aug. 2.
Virginia Int’l Raceway kicks off the second half of the season on the weekend of Aug. 21-23. While VIR hosted IMSA Prototype Challenge in 2018 and 2019, the series was not originally scheduled to visit the facility this year. However, the VIR round replaces the Canadian Tire Motorsport Park event that has been canceled for this season.
Mid-Ohio Sports Car Course will host the penultimate round of the season on the weekend of Sept. 25-27, with the season finale set for Michelin Raceway Road Atlanta on Oct. 14-17.
Aside from January’s Daytona event, all other IMSA Prototype Challenge races will be one hour and 45 minutes in length.
