Hope you enjoyed it. I enjoyed this ride several times over the years and used it as "big ride" for medium-sized children. Trouble was once I'd run out of kids even a old, fat, unfit git like me found it very short, flat and easy and ultimately not worth getting up on a Sunday for - especially when you cycle over most of the route at the western end on a regular basis.
It's a nice introduction to some of London's landmarks if you are not blessed with the chance to live in our great capital cityl
