An alternative map of the London Underground has been published showing the number of paces required to walk between stations.
The central London Tube map has been adapted by insurance firm PruHealth to encourage people to take more exercise.
It estimated the average person would take 99 steps in walking between Cannon Street and Monument stations and 2,438 steps from King's Cross to Farringdon.
The British Heart Foundation recommends walking 10,000 steps per day.
PruHealth said it would take the average person 75 minutes to walk that number of steps, but it would help protect them from stroke, diabetes and some forms of cancer.
The alternative Tube map was compiled for the firm by volunteers using pedometers.
Chief executive officer Shaun Matisonn said: "There does seem to be a misconception as to how much walking one should ideally be doing each day and the answer that it is 10,000 steps is sure to come as a big surprise to many.
"It would be hard for anyone to hit this target immediately, but small changes are all steps in the right direction."
