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. Following in the footsteps of the literary walkers, Day explores the connection between cycling and writing, and in the history of the bicycle he reveals also the history of the landscape. The great bicycle road races – the Tour de France, the Giro d’Italia, the Vuelta a España – are exercises in applied topography. Cyclogeography explores the relationship between bodies, bikes and geography.
