Should you? I have had the start of a cold for a few days now. I have still run as usual. Found it a little bit more hard going than normal but still enjoyable. Funnily enough, when I think about going to work I feel quite unwell with my "cold" but when I think about going for a run, I feel not too bad and am raring to go. As a newbie I haven't had any illness since I started running this summer. What do the rest of you do if you are a bit under the weather? Train through or rest up?
