“ The course covers ten kilometres [6.2 miles] , of which 41⁄2 kilometres consist of a track and the rest of a road circuit. Hitherto, motor races have been run either on open road circuits adapted for the occasion, as in Italy and France, or on closed tracks, as at Brooklands and Indianapolis. The Monza track combines the two, giving greater safety and at the same time the possibility of reaching high speed. Cars can pass from the track to the road circuit and cover the whole ten kilometres without interruption. Stands with accommodation for twenty thousand people have been built. ”
