Our next update will be after the conclusion of the race at 2:30 p.m. ET. Please check back then.

The Rolex 24 at Daytona has less than one hour to go, and excitement and anticipation is building to see who the winners will be in the three classes.

Here’s the leaders for Prototype, GTLM and GTD:


No. 5 Mustang Sampling Cadillac DPi, Felipe Albuquerque

No. 54 Core Autosport, Oreca LMP2, Colin Braun

No. 31 Whelen Engineering Racing DPi, Mike Conway


No. 67 Ford Chip Ganassi Racing, Ford GT, Ryan Briscoe

No. 66 Ford Chip Ganassi Racing Ford GT, Joey Hand

No. 3 Corvette Racing Corvette C7.R, Antonio Garcia


No. 11 GRT Grasser Racing Team, Lamborghini Huracan GT3, Mirko Bortolotti

No. 86 Michael Shank Racing with Curb/Agajanian, Acura NSX GT3, Alvaro Parente

No. 33 Mercedes-AMG Team Riley Motorsports Mercedes-AMG GT3, Jeroen Bleekemolen

Of note, one thing that could impact the final hour of the race is rain. It began to rain lightly with about five minutes left in Hour 23. The weather forecast/radar indicates a large storm to the west of Daytona.

Below is a report on notable happenings from Hours 21 through 23:


Given that there have only been four full-course cautions (for 28 laps) thus far in the first 23 hours, a new record for most laps and longest distance run in the Rolex 24 appears very likely.

By comparison, last year’s race had 21 full-course cautions that impacted nearly half the race (298 laps).


The No. 5 Action Express Mustang Sampling Cadillac Dpi came into the final four hours of the race hopefully having overcome what had been a troubling overheating issue between Hours 17 and 20.

“It seems to be under control,” one of the three co-drivers, Christian Fittipaldi, said on FS1. “We’re trying to make it as much as we can. … After we came into the garage, we think we found the solution and now we’re just working according to our expectations.

“If you look at it historically, this race has a lot of yellows. But for one reason or other, we’ve had, what, 2-3 yellows? This thing has turned into a 24-hour sprint.

“At some point, the machinery is going to give because we’re used to having a lot more yellows than what we’ve had. At the end of the day, it’s the same for everyone and we just need to make the best of what we have.”


With the No. 23 United Autosports Ligier LMP2 Prototype suffering a number of issues during the first 20 hours, two-time Formula One champion Fernando Alonso has had to adjust his hopes and expectations for the remainder of the race.

“I think now the goal has shifted to just finish the race, my first 24-hour endurance race,” Alonso told FS1. “We have too many issues to have any possibility to fight for a top position. The puncture, the brakes then the throttle, a little bit of everything.

“The pace was there. We didn’t have the pace in practice and qualifying, but today we were very competitive. We were second-third fastest. At least a podium was a possibility.

“It was a shame but nevertheless, I’m having fun. I’m sad when there’s a driving change, I don’t want to get out of the car because when I’m driving it, I’m enjoying it. It’s been a nice experience. Hopefully, now we’ll see the checkered flag. That’s the goal.”

Alonso put to rest speculation about whether he’ll be back to try the Rolex again.

“It’s been a good learning experience and I can’t wait to have another go-round in the 24 Hours,” he told FS1.


Former IndyCar driver and current NBC Sports IndyCar analyst Paul Tracy had a number of interesting things to say during an interview on FS1.

Among the topics he discussed:

* On A.J. Allmendinger: “This is no slight to A.J., but I think if he had not been stuck in mediocre Cup programs the last five, six years, I think he could have done amazing things in road racing, IndyCar, maybe even get to Formula One. But he went the Red Bull route and kind of got stuck in this no-man’s land of NASCAR. I think, his career, with so much more results, I think he could have had had he not gone in that direction.”

* On Helio Castroneves switching from IndyCar to IMSA: “Obviously, those guys are in their 40s now, so it’s not going to go on forever in IndyCar. The talent level now in the younger guys that are coming up like (Josef) Newgarden, those guys are the best of the best. No doubt that Castroneves still has as much speed as anyone out there, he was almost on the pole for this race. So, changing from one type of car to another and then immediately almost being on the pole the first race, he’ll continue to run in this until whenever he wants to stop driving. Until he tells Roger (Penske) one day, ‘Hey, I’m going to hang up my helmet,’ he’s got a ride.”


Scott Pruett is in the final hour of his 50-year racing career.

Pruett will retire after today’s checkered flag drops. He looks loose and relaxed and even with how key this race is to him, he’s still the quintessential teammate.

“It’s been business as usual,” Pruett told FS1. “We’ve had just an up-and-down time, coming out of the box Lexus was running real strong, running top 2 and top 3 with both cars, had some issues, stayed in the top 5, had some other issues. But it’s been great. You never know what’s going to happen in this race.”

While trying to put his retirement aside until the race is over, Pruett still did get a little wistful talking about being at Daytona one last time for one last Rolex 24.

“The memories here, the experiences here, the fans here, are second to none,” he told FS1. “I’m so proud to be a part of it. For my last race, I couldn’t think of any better place to be.”

Pruett isn’t scheduled to have one final stint in the No. 15 3GT Racing Lexus RC F GT3, but that could change. He knows the significance of finishing for teammates David Heinermeier Hansson, Dominik Farnbacher and Jack Hawksworth for the overall IMSA WeatherTech SportsCar Championship points.

While it would be a great way to finish his career driving the last laps of today’s race, Pruett is still the consummate teammate.

“It kind of depends on how things unfold,” he told FS1. “They wanted to (have him drive) but because of rotations and some other stuff, and these guys are with Lexus and 3GT focus and doing the best they can in the championship for the whole year, we’ll see how it goes.

“I’m ready to go in if they need me.”


It won’t be the finish that Roger Penske and everyone associated with the new two-car Acura Team Penske wanted, but he’s looking to going forward.

“I think the race has been amazing, fast cars, everybody’s been racing hard the whole day and night,” Penske told FS1 “We had an alternator go out on one of the cars and Helio got hit, but for us, if we can finish the 24 Hours and we know we have some speed in our cars, we’re looking forward to get to Sebring (next race on the IMSA schedule).

“But this is a great test for us, endurance, our pit crews and for Acura to have something as good as they’ve given us is terrific.”

Houston Supercross by the numbers: Five riders begin to gap the field


Chase Sexton stumbled in San Diego and Eli Tomac had a hard fall in Anaheim 2, but the Monster Energy Supercross numbers for Houston suggest they will continue to be the ones to beat in Houston. To do so, they will have to turn back challenges from another pair of riders who have swept the top five in the first three rounds and another with a worst finish of sixth.

Despite an accident in his heat in San Diego that sent him to the Last Chance Qualifier (LCQ), Sexton recovered to score a top-five that weekend. His podium finish in Anaheim 1 and overall win last week in Anaheim 2 makes him one of the three riders with a perfect top-five record. He is joined by Cooper Webb, who finished second in the first two rounds and fourth last week, and Ken Roczen, whose consistency in the first three races contributed to him grabbing the top spot in this week’s NBC Supercross Power Rankings.

There are reasons to believe Webb and Roczen can keep those streaks alive.

Webb is the only multiple winner at Supercross’ current Houston stadium. His pair of wins came in 2019 and 2021, the same year he won his two 450 championships.

Clinton Fowler points out this week, that Webb has carried that strength into 2023. Webb had a late surge in Anaheim 1, advancing from fifth to second in the final six laps. In San Diego, he set his ninth fastest lap with two to go and his eighth fastest on the final lap. He posted his fastest lap of Anaheim 2 on Lap 12 while the rest of the field did so on Lap 6 on average.

By comparison, Tomac set his 14th fastest lap on the final circuit in route to winning the Main at San Diego while he was trying to keep Webb at bay.

With a sixth at San Diego, Dylan Ferrandis barely missed sweeping the top five in his first three races as did Tomac with a sixth last week at Anaheim 2.

This will be the 46th year Supercross has visited Houston and with 55 races the city is tied for the second-most with Detroit.

Jim Pomeroy won the first race in the Astrodome during the inaugural season of 1974 on a 250, which was the premiere class at the time. Houston was one of three races held that year along with events at Daytona International Speedway and the Los Angeles Coliseum. All three venues return in 2023 with the first SuperMotocross championship finale returning to the famed LA Coliseum in September.

Webb won most recently in 2021 in the final race of three held there that year as the series executed a strategy of racing in residencies to limit travel during height of the COVID-19 pandemic. Tomac and Justin Barcia also won in Houston in 2021.

Two privateers have started the season on a high note.

Joshua Cartwright and Joshua Varize have each made the last two Mains. Cartwright finished 18th in San Diego and 21st last week in Anaheim 2 – all while working fulltime as a Business Intelligence Analyst at the University of Texas, Dallas. Varize earned a top-15 (12th) in San Diego and was 21st in Anaheim 2 in his third season on a 450.

The numbers show none of the active 250 Supercross East riders have won in Houston, so no matter who steps on top of the box, there is going to be a fresh face. That is not surprising since most of the top competitors have not raced at this venue yet.

Michael Mosiman has a pair of top-fives there, however. His best finish was a second in the second 2021 race. Garrett Marchbanks scored a top-10 in his rookie season of 2019 in Houston.

In the 250 East division, Hunter Lawrence is one of the favorites to win the title now that Christian Craig has moved to 450s. Last year he had four wins and nine podiums, but failed to set a fast lap in a race.

The other 250 riders with 2022 wins this week are Mosiman, who earned his first Supercross win last year in San Diego, and Nate Thrasher, who became the fifth new class winner at Daytona.

Jeremy Martin will attempt to extend a record this week in Houston. His division leading SuperMotocross podiums number 65. He has 26 wins in the combined sessions, which ranks fourth all time.
