I done it! I ran 32 minutes in total covering 4.25K. The weather was loads cooler around 18 degrees and cloudy which was lovely. My breathing is still rubbish from the 1st minutes and I think that is the main thing holding me back as my legs would probably keep on going. If feels like my windpipe is being squeezed. I used to be asthmatic as a child and also all my years of smoking (do not now), so am wondering if these are factors, or it is generally still being unfit and it will take time to build. I am still running on completely flat ground and will do until I feel better with my breathing. All in all though a better run than the ones in the heat. Oh and it started to rain just as I finished which was lovely to cool down in. Perfect timing!
