About Blue Marble Radical Cup North America

The Blue Marble Radical Cup North America series is the continent’s premier Radical championship, offering multi-class Le Mans style racing for a fraction of the price at iconic circuits including current and former F1 and INDYCAR 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. Sanctioned by USAC, the series will be showcased at a number of INDYCAR events in 2023. The Radical Cup caters to drivers from novice to veteran, karters looking for the next step in their career and country club or regional racers looking to step up to true national competition. The series has a growing list of impressive alumni including multiple Le Mans drivers as well as national and international champions.

Radical is the only prototype manufacturer to offer a premium factory supported single-make series on multiple continents, all with GT eclipsing performance but without approaching anything like a GT budget. The on-track competition in the Blue Marble Radical Cup is matched by the off-track camaraderie, and we pride ourselves on the family feel of our paddock, where privateer and family efforts are just as welcome as professional and dealer teams.
