I tried "in through the nose, out through the mouth...cant do it. Snot and lack of air...I'm a former swimmer, so I'm just used to in and out the mouth. That being said, when I take larger slower breaths and concentrate on it, I go faster, usually 1 to 2 mph, and my legs feel like they have more in them. I guess the consensis is slower, larger concentrated breaths=more O2 to the engine. Makes sense to me.

Question: Who slows down their breath without thinking about it? I have to make a consious(probabally spelled "consious" wrong) effort in slowing down the breaths.
