Individual dates have come out along the way, but now the Pirelli World Challenge has officially confirmed its 2015 schedule in full (save for one to-be-determined TC/TCA/TCB race weekend).
PWC and IndyCar share the docket five times (St. Petersburg, Long Beach, Barber, Mid-Ohio and Sonoma), and the championship branches out on its own for five standalone weekends.
The series reprises its standalone roles at Canadian Tire Motorsport Park (May), Road America (June) and Miller Motorsports Park (August), the latter event moving from its September date this year. Meanwhile Circuit of the Americas (March) and Mazda Raceway Laguna Seca (September) return to the schedule for the first time since 2013 and 2012, respectively, to book-end the season.
Full release here from the PWC website. Meanwhile, a schedule breakdown is below:
