This description didn't originate with me, but it is the best way to describe DailyMile: It's Facebook for runners.
(If you're not already on DailyMile, I highly recommend you checking it out.)
Anywho, every day DailyMile asks a new #dailymission. What it is is a question or comment regarding running. One day they will ask, "what's the one piece of running gear you can't live the house without?" Another day they'll ask, "morning, noon or night? When do you like to run?" For the most part, I don't respond or comment on them. But every once in a while, they have one that peaks my interest. Today's #dailymission struck a nerve with me. So much so, I felt a blog post was in order to fully share my response.
