I propose an 8 mile walk around Eartham and the Slindon Estate on Friday 14th September with a fall-back date of Friday 21st if the weather is not good. The route includes a chunk of the Stane Street Roman road which is traffic-free.

I plan to do a recce walk between now and then. If you can't make the proposed date (or you'd like to do the walk twice!) let me know - I'd welcome the company.
