That was a great walk - thank you Clair and Claire.
Two versions to view the route of the walk:
1) link to GPSies - you can fiddle around and maybe view with Google Maps - Earth option gives isometric perspective.

2) link to OS Getamap - requires download of Microsoft Silverlight - not too big a file, 6ish megs.
Suggestion: maybe try Leisure view.

Anorak tip: at the end of the walk, seated in the very pleasant Swan Inn, train times were accessed using phones. Recently I came across a fast convenient way of getting trains time, especially if you plan ahead and store journey details.
The main site is (N.B. as is - do not put in www://)
traintimes.org.uk
But a really useful feature is to save bookmarks of journeys.
e.g. I have saved 2 bookmarks for travel to and from work - the to work bookmark - Shoreham to Havant is traintimes.org.uk/sse/hav or less anoraky, cagouley perhaps?, if you don't know the rail station shortcodes, traintimes.org.uk/shoreham-by-sea/havant
