Why does my throat hurt after I run for about 5 minutes?
Because you are breathing through your mouth and drying out your throat. Try pacing yourself and breathing through your nose.
If its really cold
not enough water, allergies?
Your probably breathing hard. It will stop eventually, keep up the good work! :)
When you run try keeping your mouth closed so the air wont get in through your mouth only you nose
Need some water take some allergy pills just to be safe(:
