I sit here on the eve of my first half marathon, butterflies in stomach, thinking of what got me here. The short answer is, a few months back I decided “Why not?” and started training. It was far deeper than that though. I didn’t sign up for the race right away. I also didn’t tell people right away. Why? Accountability. I wanted the ability to bail on this venture (I have before shortly after the start) without feeling overly disappointed in myself.
