I made a decision this morning. Unless I am so ill I can't contemplate running, I am going to make the effort. Unusually I felt really tired and wasn't sure if I felt like getting up to run. Normally on a Saturday morning I'm wide awake anyway, and I just think it's better to run for half an hour than to fiddle about on Facebook. So even though I could have very easily just rolled over and gone back to sleep, I pulled on my trainers and went. It was so worth it. Week 4 in the bag, and week 5 starts on Monday!
