Well I got up this morning at 5.30am to do wk5 run2. I managed run1 quite effortlessly, but this morning I couldn't even run for 4 minutes. I just could not breathe. I was really disappointed getting up at that time just to fail. I will go back to run1 again I think, although I do feel quite wheasy still. It didn't help that I had problems with my treadmill so had to go outside. It just wasn't meant to be this morning.
