I started running recently and noticed the zone dawning upon me already. I run around the same path every time (a 3km trail) and try to enhance my performance while evening my pace, so I'm pushing myself. Yet there's a long straightaway where I often start to feel it come in as some sort of positive dizziness creeps in my body and mind (I feel 'lined up' with myself like every part of me is focused together), and the next thing I know I'm 1km later, with a much faster pace than I could expect and a feeling of smoothness and easiness.

I can assure you that it is just as discernible in programming, but I suppose different people experience it with different intensity on the same activities.
