Good news for commuters: you could be accidentally walking the equivalent of a marathon every single fortnight.

New research undertaken by Macmillan Cancer Support found that one in nine commuters walks for around 40 minutes every day as part of their total commute.

This time spent walking is the equivalent to covering a distance of 2.6 miles, which adds up to a whopping 26 miles – the distance covered in a marathon – every fortnight.

The study included travelling to and from transport as part of the distance covered, as well as walking between trains, climbing up escalators and hitting the stairs, showing that it all adds up.
