Interesting article from Runner’s World. I’m sure this is some truth to this as it has been backed up scientifically, I just think it’s hard to “force” your breathing pattern.
Just before you crest a hill or reach the end of a speed interval, your lungs go into overdrive. Your breath becomes shallow and rapid. You think if only you could pull in more air, you could surge up that hill or maintain your pace. But the more your chest heaves, the more you struggle. You may even end up exhausted, bent over, gasping for air.
