2023 iRacing Rolex 24hrs of Daytona Recap

After 24 hours the team came in 6th. It was quite the comeback having been bumped into before the start and dropped to 24th(last in class). They spent the hours moving up to 3rd, but crashed shortly after mid-night requiring repairs. Congratulations on completing the race and a great comeback.

2023 iRacing Rolex 24hrs of Daytona

2022 Recap

The 2022 season was a real mixed bag.   It started off with some great promise. Jason raced with the Road To Indy eSeries and spent a lot of time practicing with the Road To Indy USF Juniors only to have that collapse at the first race.   He then pivoted to racing Spec MX-5 Miata which went reasonably well, though he did crash twice.  The season was capped with a great weekend racing a Spec Racer Ford and then 4 days of testing in a USF Champions USF 2000 at Indy.  All in all while it was very challenging to pick up new cars and tracks, Jason made the most of it.

“The year brought on a lot of challenges, but, I think, the fact we are still racing means that 2023 will be that much better” – Jason
