Stewart Eyes Hat-Trick at Stewartby Finale

Stewartby Water Sports Club hosts the decisive final round of the 2025 GT15 British Championship this weekend, where Poppy Stewart will aim to secure an unprecedented third consecutive title before her planned transition to the GT30 class.

The 14-year-old from Lowestoft arrives at the Bedford venue with a commanding 12-point advantage, but the two-time defending champion faces determined opposition from five rivals who will throw everything at preventing her coronation.

Stewart’s Swansong

Stewart has dominated proceedings across the opening two rounds, claiming maximum points at both Lowestoft and Lancashire to establish what appears an unassailable lead. Her performances included pole position bonuses at each event, underlining the speed advantage that has characterised her reign atop the junior ranks.

The British and World GT15 speed record holder requires only a podium finish to mathematically guarantee the championship, though her rivals will be banking on the unpredictability of circuit racing to produce an upset.

Victory would mark a fitting conclusion to her GT15 career ahead of next season’s move to the more powerful GT30 machinery.

Battle for the Podium

Whilst the title appears destined for Stewart’s trophy cabinet, the fight for championship silver remains wide open. Millie-Rose Bowman and Tate Mantripp share joint second on 30 points, with Riley Hudson and Zachary Jelf locked together on 26 points in fourth.

Just four points separate second from fourth place, guaranteeing a fierce scrap for the remaining podium positions. Both Bowman and Mantripp are chasing their maiden Grand Prix victories, whilst Hudson, the 2023 champion—and Jelf—last year’s sprint champion—bring proven winning pedigree.

Championship Mathematics

With 21 points available for a perfect weekend (20 for victory plus pole position bonus), mathematically any driver from second to fourth could still claim the runner-up spot with a strong performance.

Rookie Entry Completes Six-Strong Field

Jack Roberts makes his British Championship debut this weekend, having completed his GT15 training at Stewartby in July. The JC Racing Team driver recorded a creditable fourth place finish in his club racing debut at the venue in late September, providing valuable track knowledge ahead of his step up to national competition.

Roberts joins an exceptional field where the youngest competitor—10-year-old Bowman—currently holds joint second in the standings during her debut season, whilst 11-year-old Mantripp brings the added pressure of being the youngest ever powerboat speed record holder.

Club Commodore Nigel Edwards said:

The junior racers have excelled this year, they have all raced fantastically throughout the season and we will end the season on a high this weekend as we declare the 2025 CPA British Champion.
