Thanks Wobbled, I think I might try that next time - it was dodge the tourist until after the Eye. I took a slight detour through a little housing estate in Battersea (I think someone had been playing with the signs), but otherwise I got from A to B without too much trouble and will try it again. I'm trying to practice running on the flat to pace myself better for my upcoming half marathon. Whilst running around where I live is lovely, it is all hills and as soon as I get on the flat I have no idea how to pace myself properly.
