I can't believe it, I finished and can run for 30 minutes non-stop. I just need to remind myself how difficult I found 3 minutes running just a few weeks ago. This has been life changing for me, giving me health, confidence, routine, enjoyment (well, sometimes) and a renewed self esteem. I am more proud of myself during the C25K than I have felt in a long, long time.
Thank you all for all the inspiring posts, advice and encouragement.
