Always enjoy the Festival, now it's back to the FF1600s.
The following weekend is the Walter Hayes trophy at Silverstone which is now the bigger event, but this year it's closed to spectators - as all Silverstone's meetings have been this year. Silverstone - the home of British motor racing - being the only circuit you couldn't actually see any racing this year.
Still, in a couple of weeks you can spend time in close contact with thousands of sweaty, heavy breathing people at the "Run Silverstone" 5k, 10k or half marthon:
