The capital ring route is 125km (78miles) long, mainly through parks and open spaces, and mostly following pleasant residential roads in between. The route is an initiative of the London Walking Forum, which co-ordinates work among the boroughs to provide uniform signage and leaflets.
The official start and finish of the circuit is on the south side of the Woolwich foot tunnel, but you can join and leave at any point. Ealing parks are involved in two sections of the capital ring route, walks eight - Osterley Lock to Greenford and nine - Greenford to South Kenton.
More information on all walks within the ring route is available on the Transport for London website.
