Didn't even manage 1k before I ground to a halt as whole body fely like lead. Managed to get going again but only for 500m and then I gave up. Disappointed is not the word for it. Was all rather odd, just didn't feel the usual energy when I started and stragely enough I didn't even get into a sweat before the legs decided they just wouldn't go on.
Last week I did the three wk8 runs and all were ok, fun in fact, but after 3rd run I did have sore knees and thighs but that pain was gone today and didnt come back in run, I just ran out of energy and couldn't motivate myself to push on. I did spend 5 or so hours walking every day last week on holiday and had an overnight flight back from US Friday so maybe I was just pushing myself too hard, but annoyed anyway at the failure.
Will eat properly today - which I didn't do yesterday - and make sure I'm properly hydrated and mentally focussed tomorrow and will give it another go. Not going to be defeated again by lead like legs. Time for porridge and some chocolate me thinks.
