Frank is a legend around here (I live about an hour from his store). This video shows the running style you need to have to get across the US quickly. He floats like a butterly without any energy exterted.
That's very cool to watch. His style is half-way between a Japanese elite marathon (very short strides and little knee lift) and a race walker, with very smooth leg action.
I'm still getting over the footage of RY struggling through a four minute time trial for the camera, looking like he is about to die.
