Difficult but done. On the positive side my brisk walk speed has really increased, from 5.3kmph back in week 1 to today's 6.4kmph. That encouraged me to up the speed on the run to 7.8 ..not too much more but enough to show I can do more. I dropped back down to 7.5 on the second 10 mins as I was really feeling tired, but I'm pleased that my usual speed has now become my tired speed; that's progress I think!
My breathing is somewhat laboured, though not bad enough to quit, I'm really huffing and puffing during the walk.
Why has week 6 felt so tiring? Can I do 25 mins on the next run? To be continued .....
