Kona 2011: Running Technique Footage

Recently I came across some footage from Kona 2011 that I thought I'd re-blog and share for all those who are interested in taking a closer look at the running form and efficiency of some of the world's top Professional Ironman athletes.
The two clips below come courtesy of the guys at ttbikefit.com and were filmed at 300 frames per second to provide the smooth, slow motion playback.
The male athletes shown, Crowie, Dirk Bockel, Mike Aigroz, and Timo Bracht, were all filmed on the Queen K at mile 23 of the marathon.
The female athletes shown, Caroline Steffen, Leanda Cave and Chrissie Wellington, were all filmed on the Queen K at mile 13 of the marathon.

Rather than make another analysis video in the style of the our "Crowie vs Chris Lieto Running Analysis" blog post, I thought it might be fun this time to leave the discussion open and to discuss what we can all see in the comments section below.
Use the comments form below to tell us what you can see from the running techniques displayed in these videos, both positive and negative, and we'll chip in with our coaching view points also.
