Well there is Week 7 (or 8 in my case) done. I decided to do all 3 runs over the same route to see if I improved or fell back. Including the warm-up/down: 8:30/Km, 7.55,/Km, 7.50/Km. I think I was a bit too cautious on run 1, but really enjoyed the last 5 minutes - which are slightly downhill, which encouraged me for the next 2.
I know it's dangerous, but I am getting quietly confident now.
