I did w8r3 tonight and only managed a mile before stopping, just couldn't seem to get my breathing right, didn't feel I was breathing deep enough and my chest felt tight(could have been the cold air?) I fear I am starting losing my enthusiasm but I really don't want to quit. This is only the second failure as the same happened on w7r2 at the same point. Feel a bit down now and unsure if I should just man up and get out on Saturday and start week nine? Or try the same run again before progressing.
