What happened, I don't know.. I ran for 10, and then I just started walking, thinking 'nooooo whhyyy?!' - I felt knackered but did I feel SO tired I HAD to stop? I'm really not sure whether it was physical or mental! But I carried on running after 30 sec or so, for a few mins, then walked prob 60 sec, ran again.. then walked again I think? Well whatever, I didn't run for 20 is the main point here! I thought I;d be able to do push myself to do it but no...how annoying. My bf said I should go out again today which I was kind of tempted to do but didn't want to risk 2 fails in one day, and thought it might be even harder 2nd time round as my leg muscles would be tired. So I will attempt it again on Tuesday, hopefully my annoyance will get me through.
