The Radical Challenge returns for its 20th season as Radical’s premier UK & European race series.

Officially the UK’s fastest single-make sportscar championship, the highly competitive Radical Challenge continues to showcase pure driving talent, and is fully factory supported by the biggest sports prototype brand in the world. Under controlled ‘spec racer’ regulations including factory sealed engines, the Challenge is the perfect championship for the experienced national racer to go to the next level with true downforce racing at lap times faster than BTCC & GT4 cars.

The Challenge format continues in 2021 as a mix of sprint races with a longer endurance length finale. This format supports both Solo drivers and 2 driver teams, who can share the race time equally.

The Challenge events will burst into action on Saturday with morning qualifying and two 25-minute sprint races, whilst Sunday’s racing sees the introduction of a second 15-minute qualifying session to determine the grid for that day’s 45-minute endurance race, including a mandatory pitstop/driver change for teams. Sunday’s racing will count for as many points as Saturday – so if you’ve had a nightmare first day, you can make amends on the second.

In-line with Radical’s other international championships, the Challenge welcomes back the Masters Class to the UK after a 5-year hiatus. For the first time this will feature the awesome new turbocharged Radical SR10, as well as allowing Radical SR8, RXC and RXC Spyder models to join the Challenge grid. Solo drivers and driver teams can continue to contest the longstanding Supersport class for SR3s of all generations, including the recently-launched SR3 XX.

Radical Championship Teams


Superb new additions to the Radical race mix for 2021 are the Club Sprint & Club Enduro Cup titles, specifically aimed at the ‘Clubman’ SR3 1300/1340cc competitor.

These allow solo drivers to compete for honours within the Challenge weekend framework at a lower budget level, contesting just the Saturday Sprint or Sunday Enduro racing programmes – or both - for independent Club Cup trophies. 
Specifically formulated to help the privateer and self-run competitors as well as those looking to enter SR3 competition for the first time, Club Sprint and Enduro affords the amateur racer additional flexibility to juggle their racing thrills with a busy home and work life, and welcomes owners of older, factory-standard SR3 models. 

Costs will be carefully controlled based on driver feedback, and we anticipate that this new streamlined offering will become a popular additional rung on the Radical racing ladder, whether for SR1 graduates, returning Radical racers from other series, and those looking for a more relaxed and flexible Radical racing experience.
