Pascal has been sim racing on the iRacing platform since 2017 and has his roots in various sprint series such as the iRacing Le Mans Series and IMSA Online SportsCar Championship. In both series, he has been able to leave a footprint of success and has even won a number of competitive races.
The Frankfurt, Germany driver made his endurance racing debut in July 2019 as he joined Mayer Simspeed Performance to run the iRacing 24 Hours of Spa with Manuel Mayer, Benjamin Fischer and Erik Teske in a Mercedes AMG GT3. Pascal was able to show off his talent immediately and convinced critics on his first endurance start, though the team did not past 13th place in the end of the race due to various crashes.
In the following Round 7 of the 2019 iRacing Nürburgring Endurance Championship, Pascal made his official debut for Fischer Motorsport, driving one of the team's Porsche 911 GT3 Cup. Ever since, the German is now competing in the same series, the iRacing Endurance Le Mans Series, iRacing special events, the DGFX ClubSport Series and the DGFX Endurance Series for Fischer Motorsport.
For the 2020 season, Pascal Theis will compete for the GT4 class championship in the iRacing Nürburgring Endurance Championship together with Canadian driver Julian Bell in a Fischer Motorsport Porsche Cayman GT4.
