Britcar 24hr (Link)
The Britcar 24hrs - the only 24hr race for GT and Saloon cars in the UK, which is now firmly placed in the British motorsport calendar as the race to attend, as a spectator or competitor. With growing grid numbers from all around Europe, and with top International teams competing, the Britcar 24hrs at Silverstone is the place to be, racing twice around the clock on the circuit lauded as the 'Home of British Motorsport', and the British Grand Prix. Going into its sixth year (it was cut to a recession-determined six hours in 2009), the event is growing each year at an astonishing rate.
