You don't have any good breathing tips do you? I feel I could improve slightly on breathing technique. I try to take big, deep breaths when running. Maintaining my pace has helped me a little....on the long runs anyway.
No, not really any techniques but I do have a few thoughts on breathing.
If you train frequently in the "anaerobic" range, meaning highly intense activity for sort periods (as in CF workouts), you don't have to worry about breathing technique. You become so hungry for air that every fiber becomes focused of pulling it into your body. This seems to make the demands of breathing during aerobic work (jogging, etc.) much easier.
I might also suggest training with a mouthpiece in or even wearing a mask (as a firefighter, I sometimes workout in my breathing apparatus). This also forces you to really focus on breathing and makes the work done without it seem much easier.
