I've had a week's break because of a cold but was back to it today and pleased to say I managed all 3 five minute runs and it was almost comfortable! Amazing! I'm really pleased as at the end of week 4 I felt I was struggling to manage all the runs and wimped out towards the end of the last run into a walk.
I'm finding that I'm always much fresher and more capable of my first run in the week not sure if this is psychological or just because a 3/4 day rest over the weekend is beneficial. Really feel the programme is working - I can't believe how far I've come from struggling to run more than 2.5 minutes a few weeks ago. However the dreaded 20 minutes is looming at the end of the week! (Gulp!)
