Silverstone Circuit
Silverstone is the current home of the British Grand Prix, which it first hosted in 1948. The 1950 British Grand Prix at Silverstone was the first race in the newly created World Championship of Drivers. The race rotated between Silverstone, Aintree and Brands Hatch from 1955 to 1986, but relocated permanently to Silverstone in 1987.
BRDC International Trophy
The event was instituted by the British Racing Drivers' Club (BRDC) in August 1949, sponsored by the Daily Express newspaper, for cars meeting contemporary Grand Prix motor racing regulations. The BRDC drew the name from that of an extinct event formerly held at the Brooklands circuit in the early 1930s. The first Silverstone event was noteworthy as it was the first to use the former airfield's perimeter roadways rather than the main runways; a circuit layout that persisted for over forty years.
