Hankook is the official tire of the Blue Marble Cocktails Radical Cup North America

The Blue Marble Cocktails Radical Cup North America is the continent’s premier Radical championship, and offers multi-class Le Mans style racing for a fraction of the price at iconic circuits across the USA and Canada, including current and former Formula 1 venues.

Ample practice, qualifying and three 40-minute races as well as trackside hospitality and social events ensures each three-day Radical Cup event is action packed, both on and off the track. Following last year’s success, the series is now sanctioned by ACCUS/FIA affiliated United States Auto Club (USAC).

The championship features three classes for the SR8/RXC Spyder, and 1500cc and 1340cc variants of the evergreen SR3.


  • Drive solo or partner up. A mandatory pitstop in the final race of each weekend allows for a driver change.
  • Supported by all Official Radical Dealers and top independent teams from across North America.
  • Events supported by factory technical personnel.
  • Unique Italian designed Libé trophies.
  • Ethanol free Gulf Racing spec fuel for consistency and fuel cell preservation.
  • Hankook Tire trackside support and free fitting service.
  • Radical Cup has produced recent champions George Kurtz (2017 PWC Champion, GTSA) and John Falb (2017 ELMS Champion, LMP3).
  • Other alumni includes David Heinemeier-Hansson (24 Hours of Le Mans winner, GTE-Am), Corey Lewis (2015 Lamborghini Super Trofeo World Champion) and Kyle Masson (2017 24 Hours of Daytona winner, LMPC).
