I have had a nightmare cold for the last week. One of those ones thats not severe but persistant. I just cant shake it. I hadnt run in a week and went out yesterday and couldnt do a mile (I was up to 5 non stop). I have entered the Reebok 10 k in 4 weeks time. Iam going to leave training for the end of the week and eat a crate of oranges in the mean time. any advice, am i doomed??
