IMSA at Road Atlanta today: How to watch, schedules, TV, stream info

Patrick Long looks back at how he maneuvered during the 2005 Grand Prix of Mosport after his seat rail broke in the car, sending his seat back and forth during the race.

More than seven months after the Rolex 24 at Daytona, the IMSA WeatherTech Championship will return today at Road Atlanta to a schedule more associated with endurance racing.

The Grand Prix will run six hours, the second-longest event of 2020 so far for IMSA since four “sprint” races of less than three hours followed Daytona in a season disrupted by the novel coronavirus (COVID-19) pandemic.

Saturday’s event is being dubbed by some as the “Petit Petit” -- a reference to the annual 10-hour Motul Petit Le Mans that will be held at the track next month.

The schedule originally would have included two endurance races by now (Road Atlanta will replace Watkins Glen and the Mobil 1 Twelve Hours of Sebring has been moved to November), and many teams are adding third drivers for the first time since the Rolex 24.

Ryan Hunter-Reay, Filipe Albuquerque, Tristan Vautier and Colin Braun are among the notables who have been added to the entry list for Road Atlanta.

Here are the details for IMSA this weekend at Road Atlanta (all times are ET):
