Hey man.
Good job on getting a camera up and running.
One note on camera - i was expecting you to run past on the tartan, not 20m away on the grass! You want the camera closer, so your head is near the top of the screen and your feet near the bottom. It will mean you’ll see less Distance, but will see more quality, even if only over 1full stride.
Or, get somebody else to operate camera.
Do you have anyway to edit the footage so it plays in Slow Mo. Or even Freeze a few frames for say 5sec or so we can see what is going on more.
Check out the following as an example - http://www.youtube.com/watch?v=8kfsX7j4ybY
Anyway - i agree totally about the ARMS. Whilst the arms are looking like that, its pointless looking at anything else. fix the arms, and other items should fix up along the way. Arms precede legs. Fix arms, then re-tape some new footage.
Would hazard a guess, if this is how you have been running, i can see why you have been getting plagued with injuries this last few yrs 
Agree with the Mirror option. CF says practice for many hrs before you even attempt FAST work when arms are in a state like yours. Use a mirror, and even a camcorder hooked into a TV set, so you can see Front on in the mirror and side on in your TV from your camcorder - all at the same time.
