Doble began his racing career in 2018 in the BMW Compact Cup, a competitive entry-level series where he spent three seasons sharpening his race craft. During this time he gained valuable experience and showed his potential as a rising talent.

In 2021, Doble took a significant step forward by moving to the Ginetta GT5 Challenge. Competing against a strong field of drivers, he quickly adapted to the new machinery, demonstrating his versatility and race-winning ability. By the end of the season, he had secured an impressive fourth place in the overall standings, confirming his status as a driver to watch.

The following year, 2022, marked a turning point in Doble’s career. Competing simultaneously in the Ginetta GT5 Challenge and returning to the BMW Compact Cup, he delivered a remarkable season-long performance. Doble amassed a total of 12 victories and 10 further podium finishes across both championships, showcasing his consistency and race-winning pedigree. His efforts culminated in an extraordinary weekend where he was crowned champion in both categories, a rare achievement that highlighted his exceptional talent and determination.

Riding the wave of this success, Doble made his debut in the British Touring Car Championship (BTCC) in 2023 with CarStore Power Maxed Racing. In his rookie season, he faced the challenge of adapting to the highly competitive and fiercely contested BTCC grid. 

Despite being a newcomer, Doble made an immediate impact by becoming the only driver outside the dominant NAPA Racing UK team to secure a pole position, a testament to his speed and composure under pressure. Although he narrowly missed out on winning the Jack Sears Trophy, awarded to the best rookie, his performances throughout the season earned him widespread recognition and respect within the paddock.

Looking ahead to 2024, Doble is set to continue his journey in the BTCC with the renamed Evans Halshaw Power Maxed Racing. With a year of experience under his belt, he aims to further improve his standings, both in the Jack Sears Trophy and overall in the championship. As he builds on the lessons learned from his debut season, Doble will be focused on moving up the grid and establishing himself as a consistent front-runner in the UK's premier motorsport series.
