Following Colin Saunders' excellent guide book, a group of us started walking the Capital Ring in December 2003 and walked it in 8 monthly stages. Seven of us did the complete ring and two others will complete it by autumn 2004. 27 people joined our group at one stage or other.
The walk, the guide book and the ability to get to each stage by public transport are outstandingly good. Thanks so much to the various groups involved in establishing this, especially the London Walking Forum.
