First Grand Prix 1950 / Circuit length 7.004 km / Number of laps 44 / Race distance 308.052 km / Lap record 1:46.286 – Bottas (2018) / The original, triangle-shaped track was built in 1921, with designers Jules de Thier and Henri Langlois van Ophem using public roads between the towns of Francorchamps, Malmedy, and Stavelot to create an amazing 14.9km circuit taking in the forests and rolling hills of the beautiful Ardennes region. The track was redeveloped in 1979, and although the new circuit is only half the original’s length, it’s still the longest on the current calendar at 7.004km.
