Circumnavigation of London – 182 miles

Is it possible to cycle around the whole of London on quiet country lanes shadowing the M25? Between Monday 14th and Wednesday 16th of September I will be finding out

Starting and finishing in Amersham, the route tracks (but remains firmly removed from!) the dreaded M25 anti-clockwise via Redhill and Brentwood from a distance of 2-7 miles with an ‘ocean’ voyage on the little known Gravesend to Tilbury ferry across the Thames.
