Cyclogeography: Journeys of a London Bicycle Courier by Jon Day.

Informed by several grinding years spent as a bicycle courier, Day lifts the lid on the solitary life of the courier. Travelling the unmapped byways, short-cuts and edgelands of the city, couriers are the declining, invisible workforce of the city. The parcels they deliver – either commonplace or illicit – keep the city – and capitalism – running.
