I caught the bus to Lewknor Turn this morning, walked the Ridgeway to the point where it crosses the Oxfordshire Way, and walked the last section of the Oxfordshire Way into Henley on Thames. That is the whole 65 miles of the Oxfordshire Way walked in five separate days-out over the course of this spring/summer.

I have mapped the footpath across Henley Park from Middle Assendon to Henley (which was missing up until now) and added to the route relation both this path and all the other ways needed to take the route from Pishill to the outskirts of Henley (ways for Pishill->Middle Assendon had already been mapped by others, but were not in the route relation).

OSM now has the whole long-distance path as a route:

osm.org/?relation=68685

I have stopped the route relation where the footpath meets the A4130 main road; there doesn't seem to be any waymarking of the trail along the streets into the centre of Henley.
