In the major event of the day, which was a 15-lap race for 1,500-c.c. sports cars, Paul Frere was dominating the race with a works Porsche Spyder fitted with the new double wishbone rear suspension until engine trouble put him out. The other Porsche favourite was Heinz with a standard car, but he was involved in a crash just after the start. The Argentine driver de Tomaso then looked a likely winner but he cooked the engine of his OSCA and had to stop for water, and ultimately de Beaufort came home first, with Isabelle de Tomaso in second place.

Other races for Gran Turismo cars were held in groups of up-to1,300 c.c. and up-to-1,600 c.c. and, as is so often happening nowadays in Europe, each class was a one-make battle. Alfa-Romeo Giuliettas dominated the small class and Porsche Carreras the large class.
