Mason began competing in karts at the relatively late age of 14, taking part in club racing before moving into car racing.[1][2]
BRDC British F3
2018
In 2018, Mason graduated to car racing, driving for Lanan Racing in the BRDC British Formula 3 Championship.[3][4] Having made his debut at Rockingham, the Brit would return to the series for the second half of the campaign, managing to win the reverse-grid race in the final round at Silverstone after it had been abandoned due to heavy rain following two laps behind the Safety car.[5]
2019
He stayed at Lanan Racing for the 2019 season, competing as the team's sole full-time entrant.[6] Despite this, Mason would manage to score three podiums in reverse-grid races, including a victory at Donington Park, where he overtook poleman Pavan Ravishankar at the Safety car restart.[7][8] The Briton ended up twelfth in the standings in a season that, given his lack of overall experience, he described as "having gone well".[9]
2020
Once again, Mason remained with the same team in 2020, this time racing alongside Piers Prior and Bart Horsten. Having been unable to prepare adequately for the season due to living with a high-risk individual at the height of the COVID-19 pandemic,[10] Mason only scored a sole podium at Donington and finished 16th in the championship, behind both of his teammates.[11]
The following year, the Brit made the switch to drive for CryptoTower Racing for the 2022 season, having stated that he had "learned a lot in 2021" and that he was "really looking forward" to linking up with the team.[13] He started out the campaign with three points finishes in Estoril, before a crash during the Pau Grand Prix.[14] Another retirement followed at Paul Ricard, caused by a collision with Alex García,[15] before Mason scored his first podiums in the series at Spa, finishing third in Race 1 and second in Race 3.[16][17] At the following round, held at the Hungaroring, Mason took his first victory, winning Race 2 in dominant fashion.[18][19] The positive momentum remained, with Mason winning once more at Imola and Monza respectively.[20][21] He ended the season fifth in the championship standings, narrowly missing out on fourth to Frederick Lubin.
Mason was confirmed by PHM Racing by Charouz to compete in the 2023 Formula 2 Championship at Spa-Francorchamps, replacing Brad Benavides.[28] He was retained for the Zandvoort round.[29] After demonstrating decent pace throughout the first two rounds, Mason was confirmed to remain with the team for the final two rounds.[30] He secured a best finish of twelfth in the Monza feature race and placed 23rd in the overall standings.[31] He was set to remain with team for the 2024, but plans fell through due to funding issues.[32]
