I found this 12 minute video looking at running efficiency extremely interesting and thought you would get something out of it too - enjoy!
Keep in mind that the variables discussed in this segment hold true for all runners - not just the Elites. I recommend taking one of the variables analyzed and work on improving it in your own running.
You will be amazed at the difference it make. Not only will you be able to run more efficiently (less fatigue associated with running), but your body will be far happier - less muscle soreness, less muscle fatigue and ultimately, fewer injuries.
