Glad you had a great run Sticky! Sounds like you took in all sights and as you crossed over the Thames so many times are you sure that they weren't the same tourists?
And thanks for allowing us to indulge ourselves in runs along the Thames! Can agree with Curly re London Loop as living close to it I've ether walked or run a few of the links.
Where do you come from Sticky? Perhaps one day you can return the favour!
