The Chiltern Way Southern Extension in and around my area of South Oxfordshire is incomplete. I want to walk it in stages in order to make a useful relation in JOSM. Last week, I walked out and back between Rotherfield Peppard and Bix, a total of eight miles. Yesterday, I walked between Bix and Upper Maidensgrove, near Russell's Water, a similar overall distance, where the Southern Extension meets the main Chiltern Way.
