Typical expenditure for running a Tube line

One of the things I enjoy most about my latest challenge – to run the length of every Tube line in London – is its simplicity. And part of that is the low running cost (note the pun).

Thus I present to you today the expedition budget for a typical day spent running the length of a London Underground train line:

–

• Transport to/from start: Bicycle – Free
• Transport back to start from end: Tube – Free (courtesy of Transport For London)
• Hydration: Tap water – Free
• Nutrition: 1 pack fig rolls – 45p
• Toileting: Public, typically at train stations – 30p or free
• Equipment: Old running shoes and lycra from cupboard – Free
• Navigation (Maps): TFL Cycle Guides – Free
• Navigation (Satellite): GPS feature on phone – Free
• Comms: Mobile phone text messages to Twitter – Free
• Food consumed upon returning to the house: Incalculable
