After hitting the dizzying heights of the W1R2 milestone I already have to take a short break from running. I developed a stabbing pain below my left breast on my rest day, feeling just a teensy-weensy bit concerned I took myself off to the docs and was relieved to hear I only had pericarditis (an inflammation of the fluid sac around the heart, it's caused by a virus and not serious at all). My doctor assured me that it had nothing to do with running, however as I sat there being told I needed to lay off the running for a week or two I was hit by a very very strange emotion, one that I have never associated with any form of exercise.......DISAPPOINTMENT. Yes, with utter astonishment it dawned on me that I was disappointed I couldn't do Run 3 today. I can't over state how bizarre this felt, I'm 51 and this is definitely a first in my lifetime. Who'd have thought it? So the plan of action is to rest, get rid of this peri-thingy and then start C25K all over again in a couple of weeks. Wahay!
