miss these guys
I think it's simply a matter of leg length/levers. He has very short, stout legs. Farah and Geb and Rupp, etc., all have longer legs. It is quite impressive, as I have not seen another athlete be able to have that mobility.
This. Duncan Kibet, 2:04 guy and the all-time daisy-clipper of elite marathoners, barely lifted his heels. There is great footage of him racing James Kwambai to the line in marathon, and Kwambai is more like Bekele, while Kibet has the Tergat lope.
