I just completed week 5 yesterday
is week 7 the 28 minute jogs? I have looked ahead but can't remember offhand. I'd try slowing your pace a little if you are struggling, that's the only way I have managed so far lol, I'm simply not built for speed.
I have discovered that every week I have doubted myself and yet every week I have surprised myself and made it through, jumping from 8 minutes to 20 last week was a turning point for me, I have worried over that for weeks and yet I made it. When I jumped on the treadmill that day I already knew I could get to 10, so in my head I thought I will try to get to 15, then when I got to 15 I just kinda thought well I can manage another minute and so on, and then there I was having managed 20
It's made me realise that really I *don't* know what I am capable of, and every week now I am going to assume I can do it, and deal with it if I can't as opposed to starting the week in that unsure 'will I or won't I' sort of way.
I really think now that probably more than 50% of this is in the mind so if you can get yourself into a positive mind set I'll bet you can do it. Or you could try my back up plan which is to add inbetween weeks. I think week 6 has shorter runs for the first two sessions with a 25 min on session 3? so if I can't manage week 7 I would create a week 6.5, perhaps running 3 x25, or at least lengthening the 2 first sessions by a few mins, and build on it. I know running is traditionally connected with racing, but the couch to 5k is not a race, so in my mind I want to improve every week but it doesn't matter if I improve as fast as the voice on my App suggests me to!
That's turned into a big ramble lol, sorry about that. I guess I am excited at how far I have come and how much I feel it has taught me already. Hope you can move on soon!
