So far i've stuck with the programme to the letter and although hard I've pushed myself. Today I went out to do the 20 minute run. I was worried and I got to 14 minutes and had to stop. I was so disappointed in myself. I nearly cried and didnt really know what to do. After a few mins I ran the last minute and a half of the 20 but didn't run the whole thing. I don't know whether to try it again, repeat week 5 or just carry on and put it down to a bad day. Advice welcomed!
