Rode down half of it, it was an untarmaced farm track which could be done with care (really it was footpath only, no cars), but then there is a locked gate going across the track with no footpath / stile around it. So unless people want to clamber over with their bikes, its a no.
So the two main options are:
* Chester isn't too bad on a Saturday and its dedicated cycle paths pretty much all of the way (with some cafes in Chester). In fact you can take the Greenway into Northgate, drop down through Chester to pick up food (

* The Eureka (very good) and the A550 / A548 (not so good)
