I feel like I failed. Well I actually came back from my week 5. run 3 in tears. I only managed 10 min. It was hot and I felt like my chest was being ripped open and couldn't get a breath. I was so excited this morning when i went out. I kept telling myself I could do this. I feel like I let myself down but I seriously couldn't carry on when I hit the 10 min mark it was too much for me to hear. I just stopped as I could hardly go another step never mind another 10 min. I don't know whether to just try again in a couple of days or repeat the whole week. I didn't really want to post in case it puts other people off but I feel so gutted. I will not quit though I know its in me somewhere. I just have to find it.
