The Test of Breathing
And now you are up to the point where it is a real test of whether you have mastered the art of breathing, for this stroke requires regular and automatic breathing, with proper timing and precision on each stroke, before you will be able to swim it easily and as comfortably as the other strokes, because you cannot miss a breath or hold your breath for any number of strokes, but must take the quick gulp of air while on the side as the face is upturned just as you draw the right hand down through the water, then close your mouth, and exhale slowly through the nose while the face is under water, until the stroke is fully completed, or, in other words, breathe in harmony and in timing with each stroke.
The double-over-arm, because of the submerging of the face on each stroke, and because of the forced regularity of breathing, and no effort being required to keep the body afloat, is well adapted for swimming in rough water, as the waves will not be so apt to dash in your face and mouth at the wrong time, to disconcert you, and interrupt the regularity of your breathing.
Charles B. Durborow, conceded to be the world’s greatest distance endurance swimmer, uses the double-over-arm stroke in making all his great long-distance swims, some of which have never been made before or since by any other swimmer.
