I continued all the way along the lengthy High Street. Shortly after it left the town, the path (to the left of the road) went a little left and continued beside a main road for about 100 yards, before going down the embankment and passing under the road in the company of the river Misbourne. I then followed a drive through the gates of Shardeloes (a large white house, now apartments, that I would shortly see on top of the hillside above me) and almost immediately turned right along the drive of a cricket ground. When this came to an end by the clubhouse, I crossed the grass on my right to a pedestrian gate, and continued between fences (and under overhanging branches). After maybe a couple of hundred yards I went through another gate, entering the attractive park land surrounding Shardeloes. Initially there was an ornamental lake (formed by damming the Misbourne) beyond the hedge that I was now following on my right. After a while the path veered slightly away from the hedge to a gate in a fence. The path carried straight on across grass to join a clear track, where it continued along the attractive Misbourne Valley.

After a few hundred yards I came to a gate, at a junction with another track (Mop End Lane). I just carried straight on along the valley, now with a hedge on my left and the river Misbourne a little way to my right, Eventually the track brought me to the road through Little Missenden, where I turned left. I had to follow the road for about a third of a mile to return to where I'd parked by the village church.

The was a pleasant walk on a generally cloudy but warm day. It must be one of the easiest 15-mile routes I've walked as much of it was flat with only four or five uphill sections, none of which were really steep. Although it was all on paths I'd walked many times before, some of them I'd not walked for four or five years and the only section I felt a bit bored of walking again was the half-mile section from Penn Street to Winchmore Hill (I use it on several routes, and there is no viable alternative).
