I started running in April, when the weather was nice, but now its cold and I have some issues. I am training for my first half marathon in February. Last week had a cold, because went out for a run on a Sunday afternoon and my throat was really cold, which forced my stop after couple of miles. Run again on Monday and my cold got even worse. Hasn't run till today, planned to do a long run, but after 3 miles, my throat start disturbing me again and was forced to stop. I always breath through my mouth, really struggle if try to breath through the nose.
