Richard Long, A line Made by walking 1967, where the artist walked backwards and forwards till a line was visible, conceptual, minimalism, land art ? / by Mark Edwards

Long’s documentation (taking a photograph) of his action is both conceptual and performance but the performance has been played out and all we are left with is this image. The theory for me behind his actions goes beyond the photograph which is the memory. The relationship is in the memory why did he do this walk back and forth, what was he thinking at the time, was this intentional or just passing the time of day. Was this a therapeutic exercise for other thoughts long was contemplating at the time. He was an art student when he made this work !. Most of my unspoken thoughts happen when i am out walking running doing my daily exercise routine. Yet whats not routine is the thoughts that pop into my head nearly all about art or negative about personal stuff, why is this so ? I enjoy so much the exercise yet the path i take is in-bedded in to my subconscious i don’t need to look at a map i just go out and walk/run. My question is, are my actions and the memory art ? The thought i have on these walk stay with me long after the walk is done.
