Running has always been something pure for me, something beyond just putting one foot in front of the other. I am not sure how much i see of the world around me when i run, except when i get up early and like to feel the world, before it wakes up.
I try not to focus on my running or breathing, rather let my body tell me what it wants to do.
I have been running now for two years, and for me, it is just a feeling of release, and focus.
