I did it! I ran for 20 minutes straight! (Okay, minus a few seconds because my stupid laces untied themselves).
I was fine for the first few minutes of the run, but then I noticed my mind starting to go "You know you are not allowed to stop this time? 20 minutes... That's more than last time..." But then I told my mind to shut up. My argument: I did 8 minutes twice a few days ago. Now it's "only" that but with running the bit that I was walking last time. Haha, okay...
But this run showed that a lot of it is willpower. And I proved to myself that I have the willpower to carry on if I really want to. Even though my mind was going "Maybe walk a little after half-time?", I decided I'll see what to do when I'm there. On being there I knew I would be annoyed with myself if I'd have stopped. So i didn't.
Until - about 12 minutes in - the lace of my left shoe started to get loose. Great. What to do? Stop and risk not getting into the rhythm again? The rhythm I found by now and with that I managed to shut my mind up? I carried on for a few meters and then stopped to tie the lace. And I nearly fell over when I stopped! Ops.
But I managed to find my rhythm again very quickly and carried on. On my last run it took me 8 minutes for the part I had left. That seemed very long! But then Laura piped up with "Only 5 minutes left!" and I was reliefed. 5 Minutes didn't seem that long! And when she announced that there were only 2 minute to go, I knew I would do that! Why stop after 18 minutes!?
And just "like that" I can for 20 minutes and covered 4,3 kilometers. Seeing it like that, it isn't that far to go from there.
