Final run - lovely day - never flunked a run before - but I had to stop after about 22 mins, just too tired and also desperate for the loo (Google runners' trots!!!). I think I set off too fast (first km in about 6 mins, when I usually take about 6:40!). Managed to get home before disaster struck. I've put it down to experience, confidence is a little dented, but I hope to graduate this weekend. Any advice welcome, I do find 30 mins a challenge. How long does it take to get used to it???
