Thomas made a name for himself being extremely successful at a very young age in Endurance racing –LMP3, LMP2, and LMP1.

He made the unusual switch from karting to sportscar racing in 2016 when he was 17 and subsequently became the first driver to quickly and successfully climb up the Endurance Racing ladder set up by the ACO (Automobile Club de l’Ouest). In only 3 years, Thomas’ speed took him from LMP3 to become a professional LMP1 driver.
