Went out yesterday all prepared for week 5 and all I was doing is the first run, so not much difference to the previous weeks and I couldn't do it. I had been poorly since Wednesday with the worse migraine I've had in years but I did give myself time to recover. I started my run ok and then my breathing went off. I felt like I couldn't get my breath and my legs felt so heavy. I had to walk when I should have been running. Granted it was only about 10 seconds but why did everything just go wrong. Feeling really deflated and frustrated.
