Patrick Makau sets new Marathon world record at the Berlin Marathon. His time was 2:03:38. That’s a mind boggling 4:43 min/mile pace.
This is a very good video to analyse. At 1:20 into the video, notice how all the runners have perfect forefoot or midfoot landing. Their feet pronate and then the kick back, producing the propulsion.
At around 2:45 in the video, just Patrick Makau and Stephen Kwelio Chemlany are left in the lead. Notice how their upper bodies move while running. Their shoulders are not just square with arms moving in a perpendicular. There’s a swing to them. They cross over the chest nicely.
Around 3:05 in the video, notice how the opposite legs/hips and arms/shoulders move forward and backwards in perfect unison while rotation around the spine. His shoulders even dip a little creating that unversally powerful infinity shape.
Perfect, perfect, perfect!!
