The Tube map that shows how many calories you would lose if you walked

A doctor has come up with a Tube map that shows how many calories you would burn if you walked instead of taking the Underground.

GP Wayne Osborne found most Tube stops in Central London require a 15 minute walk to get from one station to the next. That will burn around 60 calories.

Dr Osborne is hoping people will be inspired by his map to get off a stop early and walk the rest of the way to work. But with a Tube strike scheduled to start on August 5th, millions of Londoners may be walking anyway.
