^ Technically a tow path is no right of way for riding, but depends on the tow path. There are many in the UK where you're actually supposed to have a permit to ride. Many the right to ride depends on the land it's going through also. Even the Thames is like this, though they've marked a cycle path through many parts now.
One of my locals, the Wey Navigation is a permissive access for bikes. They're allowed, but the attitude is one of tolerance and walkers, and of course those using the tow path for its actual purpose, have priority.

Haven't heard the word wazzock in years!
