He run this so fast due to force between strong and weak mind.
Something like + and - pole in electromagnetism, mostly on strong mind and then little bit on weak mind then again on strong and again on weak mind, just like all other Kenyans / Ethiopians.
Renato can explain that better. He knows secret receipt.
The older they become the faster they are that is just like that in Africa, in other parts of the world it is different - with age we become slower but Africans with help of strong - weak mind force becomes faster.
Very simple physics.
