Because if you are smack dab in the middle of marathon training you will have NONE. On the upside, you will have copious amounts of time for introspection and meditation on every minuscule aspect of life. Nothing but you and lots and lots of the road ahead. Lots and lots of yards and kilometers. Lots of them.
Needless to say, I have hit the harder half of marathon training where the namby-pambies either buck up and plod forward, or drop like flies. Most days, I would gladly be the latter, but somehow I always manage to shame myself into my running shoes. Inevitably, when my run is finished I'm so gratified that I got my lazy butt out the door. Nothing says Job Well Done quite like a sweaty sheen and dirty, dusty ankles. That's an attractive look, right? Right?
So for any of you who might have gone temporarily insane such as myself and clicked, "submit" on a marathon registration form, and are now out there pounding out their miles in the summer's blistering heat... You are not alone. And hell yeah, you deserve that extra beer. Calories be damned. >fist bump<
