I carried on running through a cold- I had a series of four races in five weeks and didn't want to miss a single one. They were all hard, hilly trail races and I was exhausted for the first two, even though I enjoyed it, having a cold made an already hard course, even worse. And there wasn't much excitement upon finishing, I was just happy it was over. I had to drop out of my third race as I was experiencing a lot of trouble breathing up the hills and almost fainted at one point. I am now going to have to give the fourth a miss and haven't enjoyed any of them nearly as much as I would like. There are times when you have to recognize you're body, and your trainers, need a rest
