As the heart is on the left side, for humans and animals, running anticlockwise makes the centrifugal force of the body to act from left to right.Whereas it is from right to left for clockwise running.
Superior venacava (the principal vein carrying blood to the heart) takes blood to the heart aided by heart suction.This vein carries blood from left to right.
Centrifugal force due to anticlockwise running helps this suction.If we run clockwise, the centrifugal force impedes suction. That is why, in olden days, health officers ensured that all carnival merri-go-rounds were run only in the anticlockwise direction.
Racing tracks, animal shows in circuses, bullock-drawn pelton wheels, all mostly have only left turns. Stairways in temple towers have only left turns for going up. Clockwise running tires people, especially, children, easily.
