The circuit was a closed-off triangle of public roads, just north of the city of Tours. The starting line was situated just outside a small borough called La Noue-Guérinet, between the villages Neuillé-Pont-Pierre and La Membrolle on the Route Nationale 158. The numbers on the map above correspond to the photographs below. The 1923 Grand Prix of Tours was much tougher and much longer than today’s Grand Prix events. In order to finish, the participants had to cover a distance of 800 km (497 miles). As the ‘Circuit de la Touraine’ had a total length of 22.83 km, (14.1 miles) this meant 35 grueling laps. On the straights some of the cars reached speeds of nearly 200 km/h (125 mph). Around the circuit. 22 marshaling posts had been installed each of them equipped with a telephone in direct and permanent contact with the officials at race control in front of the grandstand.
Come with us as we take a lap around the 1923 French Grand Prix.
