Dagenham Church/ Cross Keys pub is not on there but is a short diversion between Dagenham East and the big roundabout.
The only gravel bit is in the bike park track (well worth following to see the view from the top of the hill), the rest is paved, including the Marshes .

Big suburbia and industrial estate vibes.
