120 days until I (fingers crossed) complete the 2011 NYC Marathon. I'm already a few weeks into training, taking those initial steps in the journey of my first-ever marathon -- steps that fill me with equal parts excitement and fear.
How did this experience change my life? As I crossed the finish line and felt someone place a medal around my neck, I understood, for the first time, that age is just a number. At 50, I ran a marathon.
