Walked from Goring-on-Thames to Mapledurham and back on Wednesday. I experienced all the difficulties of trying to walk a guide book in reverse on what was quite a convoluted route! It was the penalty I paid for easier parking at Goring. The highlight was exiting a wood on top of a hill before Mapledurham and finding a seat strategically positioned overlooking a wide sweep of the River Thames. It was a beautiful sight, in spite of the fog that never quite lifted that day.
One small stretch remained to complete the Southern Extension relation. I see today, however, that user_5121 has beaten me to it! I believe, therefore, The Chiltern Way - Southern Extension relation 1721477 is complete.
