Sam Fellows

Fellows spent a brief period racing karts before moving to cars as a teenager. Fellows competed in Ontario regional endurance racing for three seasons, scoring seven podiums and three wins. He was the 2017 champion of the CASC GT Challenge Championship. In 2018, he joined Pfaff Motorsports in the Canadian Touring Car Championship, winning in his debut. He would sign with the team again in 2019 to drive in the Porsche GT3 Cup Challenge Canada, where he won the Gold Class championship. During the COVID-19 pandemic, Fellows focused on sim racing.

In 2021, it was announced Fellows would compete in the remaining eight NASCAR Piny's Series races in the No. 98 Jim Bray Motorsports with Mike Curb entry, starting at the Circuit Trois-Rivières. In his debut, he would finish in 20th. Fellows would go on to finish second in the Rookie of the Year standings. Fellows returned to the No. 98 in 2022, running nine races and scoring two top-ten finishes. In 2023, it was announced Fellows would return to the series, this time driving the No. 87 Chevrolet for the newly formed Fellows McGraw Racing. In five races, he scored a best finish of 11th. In 2024, FMR announced that Fellows would compete in the season's road courses. Fellows scored a career-best fourth place finish at Canadian Tire Motorsport Park. For 2025, the team again announced that Fellows would drive the No. 87 at all of the season's road courses. In the 2025 WeatherTech 200, Fellows, who had led the most laps, was leading on the final lap when he was moved by defending champion Marc-Antoine Camirand, and would go on to finish third.
