So, this happened.
It's on the weaker side of my body, on the leg that's lost about 10-15% muscle, just above the ankle that is losing flexibility. I wanted a permanent reminder of what's possible.
There might come a time when I can't run at all, never mind run a marathon... but I hope that even if that happens, I can still find some inspiration from this quotation.
You'll notice that it's all properly punctuated. I made the tattooist stop after he'd started just to do a final double-check that everything was right and proper. 26.2 might be forever, but so is a tattoo... so best to get it right, eh?
