I had a crack at this 14 mile route one weekday from near to Wimborne Minster to Sturminster Newton and back. I started from Pamphill just outside Wimborne Minster, tucked around the back of the National Trust’s Kingston Lacey (one of the ones where the facilities are inside the admissions desk). I rode westwards on NCR 25 which is a lightly trafficked country road leading eventually to Blandford Forum (any Radio 4 panel discussion according to the Meaning of Liff).
