Running long distance breathing?

First off, ignore the in through the nose out through the mouth idea. If that's more comfortable for you great. Fact is, it's not realistic. When you run, your body is beggin for Oxygen. Unless you have nostrils the size of a melon, I'm guessing your body would rather you have you use your mouth as the device for capturing air. In relaxation exercises it's fine, but not in running. As for number of breaths, 4-5 breaths per second is absurd. Either your watch is broken or your body is trying to tell you to knock off the breathing through the nose crap.
