This route is London's Quietway 2, running from Walthamstow in the east to Acton in the West. Please note the section from Clerkenwell through Central London to Paddington is, at time of writing, the proposed route.
The route starts at Walthamstow and heads south west to Walthamstow Marshes where you'll skirt along the edge of the Walthamstow Reservoirs. At the marshes you turn south east to follow a short section along the River Lea and the waymarked Lea Valley Walk.
You then leave the river around Lea Bridge and continue south to Lower Clapton and Hackney. Here you turn west passing Dalston and Kingsland before turning south west near Canonbury. You then head south west past Islington and the Regent's Canal to Pentonville.
The route continues west to Finsbury, Bloomsbury, Marleybone, Paddington and Bayswater where you pass close to Hyde Park and Regent's Park.
From Bayswater you head west to Notting Hill, North Kensington and Wormwood Scrubs Park before finishing in East Acton.

See the Quietway 1 for another cycle route in the capital. It runs from Waterloo to Greenwich through Lambeth, Southwark, Lewisham and Greenwich. The route uses a series of back roads and quiet streets.
There's also Cycleway 6. This one runs through central London from Kentish Town to Elephant & Castle along safer roads.
