12 Hours of Sebring Schedule

Start of last year's race

The IMSA WeatherTech SportsCar Championship season continues with one of America’s premier endurance races, the 64th Mobil 1 Twelve Hours of Sebring Fueled by Fresh from Florida on Saturday, March 19.

The sports car classic might be half as long as the season-opening Rolex 24 At Daytona, but many veteran observers describe the race on the 17-turn, 3.74-mile converted airport circuit as being twice as tough.

Race fans can follow the non-stop live action on FS1, FS2, IMSA.tv and the IMSA mobile app, from the pre-race grid and waving of the green flag all the way to the checkered flag and Victory Lane celebrations. Fans can also view 18 hours of live competition on the FOX Sports GO app with FS1 authentication.

The event also serves as the second of four races that comprise the Tequila Patrón North American Endurance Cup. It's 52 hours of speed, skill, heartbreak, and triumph, a unique competition within the WeatherTech Championship consisting of the most prestigious endurance races in North America: The Rolex 24 At Daytona, Mobil 1 Twelve Hours of Sebring Fueled by Fresh from Florida, Sahlen's Six Hours of The Glen, and Petit Le Mans powered by Mazda. Follow all the exciting action throughout the season, on FOX Sports and IMSA.com.

The weekend also includes races for the IMSA Continental Tire SportsCar Challenge and a pair of 45-minute races for the Porsche GT3 Cup Challenge USA by Yokohama, with the action streamed live on IMSA.com and the IMSA mobile app.
