I recently finished my first half-marathon, a 13.1-mile trial of discipline and perseverance. Unlike my past rollercoaster rides of inactivity followed by bursts of overachieving, this was a respectable, incremental effort of kinder steps followed by an event completed without needing four day’s rest. I will, however, admit to experiencing a migraine requiring meds and a nap later the same afternoon. And, yes, according to the data from my fitness tracker, I still overachieved, but far less than the usual gross negligence of my physical wellbeing. I still have work to do. Fitness is a process and the discipline required to stay fit never ends. So, how do I persevere? Baby steps.
