Lebbon started competing in national karting competitions in 2016. The Brit would stay in karts until 2019, when he finished second to Joshua McLean in the LGM Series.
After racing in the Ginetta Junior Winter Championship at the end of 2019, Lebbon signed up to race for Elite Motorsport in the 2020 Ginetta Junior Championship.[1] Despite being a series rookie, Lebbon won five races, four of which he won consecutively, and won the title with a nine-point gap to the experienced Josh Rattican.[2] Through that he became the first ever driver to win the overall championship whilst being classed as a rookie.[3]
For 2021, Lebbon elected to skip Formula 4, the standard entry point for upstarting single-seater drivers, and re-joined Elite Motorsport in the GB3 Championship, partnering Javier Sagrera and José Garfias.[4][5] The Brit enjoyed a strong debut campaign, as he regularly finished in the top ten in races and even scored his first podium in the reversed-grid race at Donington Park.[6] Lebbon remained with Elite Motorsport for the 2022 season. He scored four wins and finished third in the championship.[7] The following year the Brit sidestepped to the Formula Regional European Championship, teaming up with Arden Motorsport.[8] However, the season proved to be a struggle and Lebbon failed to score any points throughout the year.
Sportscar career
Having made his GT4 debut at the Hockenheimring at the back end of 2023, Lebbon entered a full season of the GT4 European Series in 2024, partnering former Ginetta title rival Rattican at Elite Motorsport.[9]
