Hello all. I've got two questions regarding the way runners run.
Firstly, what I've always thought is that stopping immediately after completing the run (1k / 2k / 3k / 5k) is bad and we should like carry on at a slow pace for some distance.
But why is it that the runners in this video stop immediately after they've completed the run? Isn't it bad for their bodies? (Once my friend even told me that they would get "rectum pus" whatever that is.)
Secondly, what I've always thought is that we should open our mouth "bigger" to allow for more intake of oxygen during the run. What I've seen in the same video is that they do not do so. Does anyone know why is it so?
