Screen eats runner

Taken nearly a year ago, this video seems to raise questions about the relationship between video screen and the action recorded. 

Out on a run, as seen by my phone

One of my first attempts at recording moving images in references to the experience of being out on a run. I attached my phone to a rope, and whilst running, pulled phone and rope behind me. The phone scuttled over the ground, looking upwards into the trees. In the final stages of the video, I lifted the phone up from the ground, and, still dangling from the rope, which made the phone spin along the vertical axis of the rope.
The video made me question viewpoints, viewers, the mediums of recording, the content of the video, all  in relationship to a running experience. Whose viewpoint does the video record? The phone's? The runner's? Does it capture the running experience? And if yes, the running experience as seen by the runner or seen be some other agent?
