With eight events spanning some of the best racing circuits in Europe, International GT Open is widely-held as one of the best GT3 race series on offer.
Each standard GT Open race weekend is made up of two races: a 70-minute race on Saturday and a 60-minute race on Sunday so competitors get two bites at the cherry. The Spa and Monza events hold a single 2hr40 endurance race on the Sunday.
