"That's not running, it's falling... with style!"

Video analysis from Nick on my before and after running styles:

Gav: running before and after

Looking at 1:40 to 3:52, first clips are me at the start of the day, heavy heel strike as I move along - all this does is put the brakes on and send impact forces up through my knees… Second section and I'm starting to get it… Now my feet are landing underneath my centre of gravity rather than in front of it, stride is now out to the back and I'm leaning forwards with better posture, allowing gravity to pull me forwards. 

To paraphrase Buzz Lightyear… "That's not running, it's falling... with style!"

Still lots to work on but I now know what I'm looking to achieve and know what it feels like to be running efficiently. I know for certain there were times during the day when I nailed it (for 4 or 5 strides!) but these didn't happen in front of the camera… so now all I need to do is practice, practice, practice. I get the feeling it will be worth it.
