There is no definition of what constitutes a stop but there is some Case Law that may help.
So a stop must not be a pause, stopping and then starting again is unlikely to count.
The length of a stop is connected to the distance being walked. These are not agreed on values but as an example; a 30 second stop in a 20m walk is more likely to be considered as significant than the same in a 200m walk.
Stops need to be added into the time that it takes a person to walk a given distance, this would be relevant to both their taking twice as long as a healthy person would take to cover the same distance and walking to a necessary standard.
