This walk starts from the car park by the Co-Op in Church Stretton and will go over the hills on the East side of the valley, Ragleth Hill, Hope Bowdler Hill, Caer Caradoc and optionally The Lawley, opposite the Long Mynd on the other side of the valley, then back on the lower path under the last two hills. There are amazing views across to Wenlock Edge  and the Long Mynd, with views into South and Mid Wales on a good day. Lovely sheep cropped grassy paths between bracken. Some super little paths and some nice woodland. Just one section on a fairly quiet road between Ragleth Hill and Hope Bowdler. Parking in Church Stretton is £4.80 all day, free 18:00 - 08:00 and all day Sundays, payable by card. Plenty of parking spaces but it does get a bit full of walkers and visitors to Church Stretton at the weekend.

but you need to be fairly keen to add 9.36km, 3 hours and 342m ascent and I imagine we won't feel motivated to do this.

I would propose a 10:30 start Satruday. Google thinks it is a 1.5 hour drive from Birkenhead via Wrexham, A5 and then south from Shrewsbury.  You will go going in the opposite direction to the hordes heading into North Wales from Birmingham. That is about as long a drive as the far side of North Wales so not as far away as people think it is, and it is a lovely area.

Doug and Gail will be in All Stretton just up the road for a Music event that weekend.  Campervans are allowed to stay overnight free of charge in the Church Stretton car park by the Co-Op if people want to stay over and make a weekend of it or arrive Friday night. There are also campsites in the vicinity and of course BnBs and hotels.
Church Stretton has several rather nice pubs.

If people staying over want a second day walk on Sunday I suggest going up one of the rather charming southern Long Mynd valleys, over the rather boring top of the Long Mynd and back down Carding Mill valley.
There are various options for this but an example is here
