They are good but the local one to me, route 55 between Chorley and Salford is signed completely randomly and just stops.
There’s a section along a disused railway that just leads to some steps with no signage and towards Salford, two separate routes use the same signage, one along the canal and one along two disused railways.
Whether signs have been installed and stolen or damaged, I don’t know but it’s very hit and miss, one section on the online map is about 3 miles away from the signed route and is on an old railway that is under 6ft of water.
