Britain's most prestigious one-off karting event returned to PF International from 31 July to 3 August 2025, with drivers from across the UK competing for the coveted GP plates. The Kartmasters GP, which allows winners to display the GP plate throughout the year at all Motorsport UK events, featured six competitive classes including WaterSwift Restricted, MicroMax WaterSwift, MiniMax 950, Junior Max X30, Junior X30 Senior, and Senior Max. The four-day format provided drivers with extensive track time, including free practice on Thursday, qualifying and heats on Friday and Saturday, before culminating in repechage races and finals on Sunday.
The event maintained its reputation as the UK's blue-riband karting competition. Motorsport UK TV provided live coverage throughout finals day, with commentary from Henry Beaudette and Andrew Mather, whilst Kai Bachini and Xander Clements delivered trackside reporting. Entry fees of £425 reflected the championship's national status, with minimum National Licence requirements ensuring a competitive field of experienced drivers.
Championship racing intensifies at Kimbolton and Whilton Mill
The Wera Tools British Kart Championship maintained its packed schedule with rounds at Kimbolton from 8-10 August and Whilton Mill from 28-30 August. The Cambridgeshire venue of Kimbolton, a former Second World War bomber base, hosted crucial mid-season rounds as championship battles reached critical phases ahead of the autumn finale.
The late August event at Whilton Mill carried added significance beyond standard BKC rounds. The weekend marked the inaugural Motorsport UK T4 'O' Plate for the Tillotson T4 Class, making history as the first official O Plate awarded to the affordable four-stroke karting category. The T4 series, which features European-style chassis paired with low-maintenance four-stroke engines, has established itself as an accessible entry point for newcomers and returning adult drivers.
The T4 Class competed in two categories at Whilton Mill: T4 Junior for drivers aged 12-15 and T4 Senior for drivers aged 15 and upwards. The inclusion of the T4 O Plate represented a significant endorsement from Motorsport UK, elevating the class's status within British karting's official competition structure.
British 24-hour endurance race tests limits at Teesside
The British 24-hour endurance race returned to Teesside International Circuit on 9-10 August 2025, challenging teams on what organisers bill as the UK's longest and fastest kart circuit. At 2.1 kilometres with an average track width of 10 metres, the demanding layout provides constant overtaking opportunities, with lap times hovering in the low 1:20s and drivers facing gruelling 90-minute stints.
The event attracted both hire kart teams, competing in rental twin-engine 200cc machines, and owner-driver entries in their own equipment. Hire kart teams paid £2,100 for four to ten drivers, whilst owner-driver teams entered for £1,250 including fuel. The track's distinctive features include the notorious Rib Bend, where karts briefly become airborne, and the challenging 'D chicane' complex at the start-finish straight.
With its marathon format requiring precise driver rotation, mechanical reliability, and consistent pace across 24 hours of racing, the event represents the ultimate test of team endurance racing in British karting. The sheer physical demands of 90-minute driving stints, combined with maintaining concentration throughout the night, separate the strongest teams from the rest of the field.
Digital racing expands reach
The KartSim Esports UK Championship, running in partnership with Motorsport UK, opened qualifications for its third round on 25 August, closing on 31 August. The virtual competition featured two categories: Cadet Karters aged 8-11 driving the IAME WaterSwift Unrestricted model, and Seniors aged 12-plus in X30 Senior karts. The online qualifiers determined the top 30 drivers in each class for the virtual finals at Whilton Mill.
The growth of esports karting provides an accessible pathway for drivers without access to physical equipment, whilst offering current competitors valuable simulation practice. With the championship finals streamed live on the KartSim YouTube channel on 3 September, the series connects professional karters with esports enthusiasts in a competitive environment.
