In 2021, Thomas had entered the WeatherTech SportsCar Championship with his team, WIN Autosport, using an Oreca 07 in the LMP2 category with Tristan Nunez as his team-mate. Thomas Merrill had competed with the crew during endurance races and Matthew Bell for the 24 Hours of Daytona.[1]
In 2022, Thomas continued his commitment to the WeatherTech SportsCar Championship but for that season, he joined the American team PR1/Mathiasen Motorsports to compete in an Oreca 07 in the LMP2 category with team-mate Jonathan Bomarito. Josh Pierson had competed with the crew during endurance races and Harry Tincknell for the 24 Hours of Daytona.[2] At the same time, Thomas was in discussion with various teams to participate in the 24 Hours of Le Mans. One of them, Algarve Pro Racing, who were in a very difficult situation because following the withdrawal of G-Drive Racing from the FIA World Endurance Championship, which it had to support technically, it found itself without a program and its existence was threatened. It was then that Algarve offered Thomas to participate in the WEC instead of only participating in the 24 Hours of Le Mans. In view of the situation and after consulting his partners, Thomas committed himself and participated in the WEC with drivers James Allen and René Binder as teammates.[3][4] At the 2022 24 Hours of Le Mans, Allen, Binder and Thomas finished first in the LMP2 Pro/Am subclass.[5]
