Again and again, Begin.

I'm a runner, but you don't have to be a runner to appreciate this.

At my first and only triathlon in 2011.

I remember when I started running (not too long ago), and how completing a 5K seemed nearly impossible.  My husband and I began with a couch-to-5K program, incorporating walking with running, gradually increasing the running portions.    

We elatedly completed a 5K.

I remember when, in an adrenaline-rush, we decided to go for a half marathon....which seemed equally insane and impossible.  We began with running 3.1 miles, which we already knew how to do.  

We joyously crossed the finish line at a half marathon.

That was a few years ago.
