Doble began his car racing career in 2018 in the BMW Compact Cup, continuing in the category in 2019 and 2020. The following year he moved to the Ginetta GT5 Challenge, ending the year fourth overall in the standings.
In 2022, Doble produced a superb season-long performance, with a total of 12 victories and 10 further podium finishes in both the Ginetta GT5 Challenge and BMW Compact Cup, to ultimately be crowned the champion of each category on the same, thrilling weekend.
In his next season Doble built on this success and took on the biggest season of his racing career to date, after confirming his seat with CarStore Power Maxed Racing in his maiden BTCC campaign. In which he was the only man not in a NAPA Racing UK car to take a pole position narrowly missing out on the Jack Sears’ Trophy.
In 2024, Doble will aim to improve his Jack Sears’ Trophy position that extra place along with moving further through the field in his second season.
