Well that was a close one... made a bit of a school boy error and started my run on a new route that had a slight uphill gradient... after the first 10mins I was ready to stop but I decided to turn around and try and re-compose myself with a slightly downhill run. Pleased that I did and I was able to complete the run and hear Laura's imortal words... still think she was talking about someone else.
I still beat myself up about my slow pace and now looks like I need to be careful about my route... but hoping that both of these will be overcome as I complete the next 9 runs of the program.
