The freestyle side breath is one of the most challenging and complex parts of the stroke. I travel around the country working with swimmers of every different age and ability level. It is very rare that I ever see anybody who has proper breathing. Most people slow down significantly when they breathe. If you haven't worked on it before, especially the timing, you probably aren't doing it right.
In the following video I go over proper breathing technique as well as the correct timing of how the breath fits into your stroke.
