Riding a bicycle round London for ten hours a day is grindingly difficult. A bike courier is paid £2-£3 per job (with a 10 per cent bonus for working a full week if you’re lucky), income can be fickle, and a slow week spent standing in the rain is no fun at all. Though it varies dramatically, couriers cover distances averaging around 300 miles a week. Couriers are obliged to deliver whatever a client wants delivered as quickly as the client requires; if you can’t get from pick-up to destination within 40 minutes, you don’t get paid. Covering London from (roughly) Wapping to Knightsbridge and Camden to Elephant and Castle, you see a lot of the city, a lot of weather, and a great many post-rooms.
