In the field corner I went through an open gateway, and turned left along a farm track between hedgerows. This soon became somewhat overgrown and no farm vehicles could have been down it for a long time, but there was a reasonable path through the vegetation. At the end of the track I turned right along a lane - I was now in the hamlet of Wendover Dean. The lane soon turned left, and then I turned right down another lane that brought me to the A413 main road.

I crossed the road and took a footpath starting a few yards to the left. This crossed a couple of empty paddocks or pastures close to Mayortorne Manor on the right. In the corner of the second of these fields I joined a track which almost immediately went over a railway bridge and then ran between hedges to reach Cockshoots Wood. As soon as I entered the wood, I took a path going right, following it through the wood until it met a bridleway, where I turned right, dropping down through the trees to reach a picnic site next to Cobblershill Lane (the car park here has been closed for a couple of years, with a barrier across the entrance, but the picnic tables are still serviceable - I stopped here to have a belated lunch, it was now just after 2pm).

I turned right along the lane, until I reached a point where paths went off on either side. I took the path going left, crossing an artificial gallop for horses, and then following a tall well-trimmed garden hedge on my right. I then turned right, following the hedge, to reach a surfaced drive near Russells Farm. I went a few yards right, then turned left (before reaching the farmhouse) to leave the farmyard. After a few yards there was a open gateway in the hedge on my right, and here the footpath switched to the other side of the hedge, with the wooden fence of some paddocks now on my right.

Beyond the paddocks, the path followed the edge of a field a short way then entered a wood (named Sermon's Wood on Google maps). Here I soon reached a path junction, where I went left and followed a path gently uphill for quite a distance through the wood. At the far end of the wood, the path ran a short distance between fence to reach a bridleway just south of Dunsmore.
