Sixteen and a half weeks ago I started training for a marathon. Like a lot of things I do in my life, it stemmed from a perspective of “why not?” The most valuable pursuits in my life have always been somewhat lofty goals that required a great departure from my comfort zone. The reward has always been life changing. Not in the epiphany sort of way, but more in subtle shifts of perspective that permeate all aspects of my life. But ultimately, vastly improve it. The three life changing events that come immediately to mind are when I flew to Nepal by myself to trek in the Himalayas, when I summited Mt. Kilimanjaro with zero training and gear that was by most considerations, barely adequate, when I hiked across Spain for a month. And soon, I believe, training for, and running my first marathon will be added to this list.
