2023 Twelve Hours of Sebring: Schedule, TV information, streaming, start times, more


Sebring start times, TV schedule: The cars and stars of the world’s two biggest sports cars series return this week at venerable Sebring International Raceway.

The 71st running of the Mobil 1 Twelve Hours of Sebring will cap a week of jam-packed track activity at the road course in central Florida. Sebring will play host to the World Endurance Championship and the IMSA WeatherTech SportsCar Championship.

The WEC season opener will be held Friday from noon to 8 p.m. ET with the FIA WEC 1,000 Miles of Sebring. The next day, Sebring will hold its annual 12-hour classic. The second round of the IMSA season will mark the track debut of the GTP premier category for hybrid prototypes.

The Rolex 24 at Daytona season opener was won for the second consecutive year by Meyer Shank Racing, which will enter Sebring after a massive penalty for manipulating its tire pressure information.

Last year, the No. 02 Cadillac Racing V.R won the premier DPi class in the Twelve Hours of Sebring. That Chip Ganassi Racing-fielded entry (with drivers Earl Bamber, Richard Westbrook and Alex Lynn) will be competing Friday in the hypercar category of the WEC opener — the first of seven WEC rounds for the No. 2 Cadillac V-Series.R, including the 100th 24 Hours of Le Mans in June.

The team, which finished fourth in the 2023 Rolex 24 at Daytona,  competed at Sebring last weekend in the Prologue, which featured four free practice sessions totaling more than 12 hours on the 3.741-mile, 17-turn track.

“It’s great to back at Sebring, where Cadillac has had a lot of success including our win last year,” Bamber said in a release. “Now we’re here with a different challenge with a new Cadillac V-Series.R and looking forward to it. The Prologue went well. We were at or near the top of the chart every session – doing long runs, learning the tires and getting in full race preparation mode because there are short practice sessions when we roll back out Wednesday and it’s right into the race. Brand new team in terms of we did Daytona but now this a WEC team with a European-based crew, so we’re all learning. Looking forward to the race.”

Said Westbrook: “It’s a whole new program, the WEC, and it feels like it. But what a start we’ve made and there is so much more to come. The whole team is just going to get stronger and stronger and I think everyone is excited. The Cadillac is really strong, but we knew that from Daytona, so we have a nice base to work with. There’s a lot to be positive about going into the race week.”

Saturday’s Supercross Round 11 in Seattle: How to watch, start times, schedules, streams


With three multiple winners now vying for the championship, the Monster Energy AMA Supercross Series heads to Round 11 at Lumen Field in Seattle, Washington.
