Ok, picture story time (!)... (the last photo is rather gross - you have been warned!)
In 2010, I was diagnosed with a relatively rare, slow-growing form of cancer and had surgery to remove a carcinoid tumour from my appendix. I had already signed up to run a half marathon four months later and was determined to still go ahead with it.
I made it to the start line and ran the race (although, as you will note from the photo below, not very fast - being beaten by a rather spry gent of a certain age...)
