Personally, I never thought about breathing on the runway. I pictured (felt) the entire run/jump/landing in my mind and then just went. In my opinion, once you start your run, thinking about breathing, or taking off, or flight, or landing, is counterproductive. While not as complicated, long jumping is like a golf swing, where the more swing thoughts you have (beyond one), the worse your swing will be. The time for technical thoughts is in practice. Form an image in your mind of your wonderful jump as you stand at the end of the runway, then let it go. If you want one mental cue, I would suggest that it be "fast-then-relax." And I will repeat: whatever gets you to and on the board at high speed prepared to jump is what you should do, regardless of "suggestions" from me, Barto, or your regular coach.
