OK - this one is a bit obscure, even for Brits (there's the first clue...). So I'll tell you that from the startline, peering down the hill, you might not believe that you're about to start a hillclimb...
Thought at first that it might be Georg Plasa's Judd powered BMW, which would probably place it on one of the European hillclimbs.... but I don't think it is.
Looks like he's got a bit of opposite lock on, so I'm still going to guess he's on one of the sweeping turns of one the European hills. Which one....
