After a few hundred yards I came to a path junction in the wood (white arrows on a tree) where I turned right. The path continued through the wood, crossing Eastfield Lane (here a muddy track) at one point and eventually reached a road. I crossed over and followed a path on the other side that went right, running parallel to the road. Across a school drive, the path went through a gate to enter the school's large playing fields, running alongside a hedge with the road on the other side, then turning left behind a row of trees. It then turned half-right to run through a large area of grassland full of buttercups and other flowers.

Across a road I continued down a track or drive into the hamlet of Blackbird's Bottom. After a few hundred yards I took a path on the left (starting at a gate set a few yards back from the drive). This crossed some paddocks to a hedge, and then continued in the same direction across part of a meadow, beyond which I turned left along a bridleway following another drive. At the end of the drive I turned right and followed a lane for a few hundred yards to reach a point named Cold Harbour on the map, where I turned left along a byway (a hedge-lined track). At its end after a third of a mile or so, I turned right along another lane. After a while I passed Cockpit Plantation on my right. One or two hundred yards after that I took an 'Other route with public access' on the left (actually going more or less straight on).
