I completed the final run this evening and I cannot tell you how thrilled I am. It represents so much to me after 15 months of tough cancer treatment - it is about strength, health, recovery and hope, whatever the future holds.
I promise anyone who is beginning their journey that it is a) possible; and b) worth it. I am well and truly converted to this running lark. Thank you to everyone who inspired and supported me on this forum.
I'll just leave this screenshot here now....
