Walking meditation guide

[Metaphor]

@irene

Is there any indication in EBT or the commentaries about the speed you should walk?

Some of this has been discussed in a previous thread:

Walking versus Sitting Meditation

I seem to have an easier time concentrating when I am doing sitting meditation versus when I am walking. I wonder if perhaps it is because I do walking meditation first. It takes some time for my mind to properly concentrate so that by the time I have finished walking and commence sitting I have better concentration. Or might there be other reasons why I concentrate better during sitting meditation than walking? Any thoughts on why I am experiencing this? Does anyone have any suggestions?
