Had two great runs with map my run failure at the end! ( I kept my phone in my pocket). I now have a huawei pro band 2 Which worked well first time out. Ave 5' 40" /km.
I watched a few videos on running coaching last night I found this one on footstrike really useful;

I have been heel striking since I started. Today I went out and made an effort to correct my posture and make sure my foot strike was mid to front foot.
It made a lot of difference, I was amazed how far past my normal turn around point I had gone before Laura said that 12.5 mins was up. I went from 6'26" mins / km to 5' 40" mins / km for the same amount of effort. I know a lot of you will know this stuff already but I hope it will be of use to some.
