This will then form a loop with the zones along the Tyldesley cycleway. I like loops
The Lancashire Mining Museum and the RHS Bridgewater Gardens are adjacent to the canal and these would also be worth zoning.
I have one request. The main towpath is on the south side of the canal. The section by the RHS garden also has a cycle/foot way along the north side, giving access to the gardens. Any zones along this section to be take-able from both sides of the canal please.
