We have gyms in town and sports clubs around, but I much prefer to get my exercise out and about using public transport and I have often advocated trains and buses as a way of helping keep fit during the normal run of things.
An app on my phone which - err - I had not noticed until recently has been keeping tabs on me and has rather confirmed some of my exercise non-regime than help keep me fit. I was surprised at some of the numbers coming out of it, but then thinking about some of the element in there - yes - I can believe them. Walks of 20 minutes to and from the station all add up, and the use of kms rather than miles gives rise to rather more impressive numeric values.
The 16.9 kms yesterday probably includes ...
2.0 Home to station
3.0 Dawlish Warren to Dawlish
1.5 around Dawlish
3.0 around Teignmouth
2.5 Marsh Barton to Double Locks and back
2.0 Station to home
... additional with around and about at various stations along the way.
