Riding the Canals, ever do it?

so you can pick up the thames easy enough at weighbridge.
From there, you can take the Thames path all the way to Putney which is a surprisingly long route compared to going direct. There is a really impressive bit of topiary along that way that is worth looking out for. Someone has carved a figure riding on a bird flying out across the river. Well, it impresses me anyway.

Alas, you are a bit stuffed for heading up river. There are a few sections you can ride between Walton Bridge and Chertsey but only a few hundred yards each kind of things. There is a one way road that follows the river for a mile or so, so if you are heading down river you are fine! From Chertsey you can get to Windsor only losing the river a couple of times. Although a lot of it from Old Windsor up is footpath only.
