A challenge

Mr Blair Henderson has been making some comments about my cycling skills.  There is only one way to settle this, a race through the urban wonderland that is London Town. I suggest that we end up at a pub so that the loser can pay the winner his deserved beer. I propose the route should be a free form treasure hunt style, visiting say 6 london landmarks, take a photo of each and then head back to the finsish line/pub. We need a third party to propose the landmarks so that neither of us can do research on the quickest route. So get your thinking caps on and most importantly, Mr Henderson do you accept! p.s. Anyone else on for a mad ride/race/pub around London let me know and its on!
