The Capital Ring is a strategic circular walking route in London, around 125 km (78 mi) in length.

Points of interest in this section include the River Brent, the Wharncliffe Viaduct, Horsenden Hill (with panoramic views) and Harrow School.

The Capital Ring's most distant part from central London is in Harrow (about 10 miles from Charing Cross).

Walk 11 starts at Hendon Park, again following the River Brent and Mutton Brook through Hampstead Garden Suburb.

Walk 13 heads east through the streets of Lower Clapton to Springfield Park before following the River Lee Navigation south through Lea Bridge to White Post Lane, near Hackney Wick railway station.

Walk 14 passes through the area used for the London 2012 Summer Olympics, including the new Pudding Mill Lane DLR station.

This walk follows The Greenway for most of its distance passing Abbey Mills Pumping Station, sometimes known as the ‘Cathedral of Sewage’, that was built by Joseph Bazalgette.

Walk 15 explores docklands with fine views over the Thames, the Royal Albert Dock and London City Airport.
