British racer Holly Miall will line up with multiple championship-winning outfit KMR Sport for her return to the GB4 Championship in 2026, in what i set to be a new step forward as she prepares for her second season in single-seaters.

The 18-year-old completed her rookie GB4 campaign in 2025 with a primary focus on development and adaptation to open-wheel racing following a car racing debut in the highly competitive Ginetta Junior Championship. Now, heading into her sophomore year in GB4, Miall returns with more defined ambitions: to fight at the front of the grid and work towards securing a future opportunity in F1 Academy.

The Essex-born driver built her foundations over two seasons in the highly competitive Ginetta Junior Championship before stepping into single-seaters last year. Her move to KMR Sport places her within one of the most successful teams in the British junior single-seater landscape.

Founded by Kevin Mills, the squad has become one of the benchmarks since joining GB4, translating its long-standing Formula Ford success into the slicks-and-wings era. KMR claimed the GB4 Teams’ Championship in three consecutive seasons from 2022 to 2024 and secured the Drivers’ Championship title in 2023, also fielding several female drivers over the last couple of years - from Chloe Grant in 2024, to Lily-May Watkins and Megan Bruce in 2025.

Miall expressed her enthusiasm for her return to the series:“I am really excited to be joining KMR Sport for the 2026 season. I’ve been watching them challenge for the title and create top performing drivers for the last three years of being on the Ginetta Juniors and GB4 circuit – they are always a top competitor and the perfect next step for my professional racing career.”

“We’re delighted to welcome Holly to KMR Sport this season", said team founder Kevin Mills who welcomed Miall to the squad, highlighting the goals for the season ahead. "After a year of building confidence in the championship, she has been working hard to take her career to the next level, and we are looking forward to supporting her development and helping her grow as a racing driver.”

With an experienced, title-winning team behind her, Miall enters the 2026 GB4 season aiming to convert her learning-oriented year into consistent competitiveness for the next stage of her career.
