With more restrictions coming in, maybe it's time to look at doing some urban walks.
When I worked in London I found some great walks, that took me off the roads. I was down there when they first started building canary wharf, so lots of dockland to explore, with little gems like the Greenwich foot tunnel, leading to Greenwich Park.
As I commented on another thread there are some great places to walk in Liverpool/ Birkenhead area.
Anywhere that has a canal is always a source of a walk.
The other week, I dropped the daughters car off for a service and made it from one end of Keighley to the other using mainly "off road" footpaths.
