I did it! I actually went out today determined to actually run 5k so I ran 12.5 times around my local running track without stopping which took me 38 mins and I did it!
I can’t believe how far I’ve come. At the beginning I couldn’t even talk through 30 secs of running and each one was a battle. I’m now a stone lighter have dropped a dress size and can run for 38 mins no stopping. Wow! Thanks everyone for all your encouragement.
