Most articles I have read indicate that when running you should breath through your nose but I just can't!
I don't feel I can breath in enough oxygen through my nose then I panic about it and start breathing through my mouth. I am an ex smoker and before I gave up (almost 2 1/2 years ago) I was diagnose with moderate COPD so ever since I started running a year ago (my GP has OK'd me to run), breathing has always let me down and slows me down. I find it particularly hard to breath in the icy weather as the intake of cold air through my mouth into my lungs really hurts my chest and these last two weeks I have been running really slow. In addition, breathing through the mouth has started to affect my throat and I have been losing my voice.
Any advice please?
