If your run fitness was a one of these mountains, which one would you rather it be? Either can have a good foundation, but one is very distinct - it draws you in. You imagine what it is like at the top. In some ways it looks impossible to climb, but if you look long and hard, you begin to see possible routes and a way to the top.
The other mountain can be much easier to get to and climb, as many people do. Less preparation is involved, with less unknown. And, it comes with a plateau.
The other, more impressive looking one is much more elusive and challenging, where most people observe from the base, snapping pictures, but very few attempt to take a "selfie" at the top. To summit, it requires knowledge, a progressive plan, and an extreme enjoyment for the process. A burning desire every morning, to wake while every one is still asleep, to train for the summit.
There is not enough room at the summit for everyone, but sometimes that is why we attempt to climb. After all, we soon realize it is the process of becoming our best that we ultimately fall in love with, and that ultimately becomes the joy of running.
Being your best is just a choice, which mountain do you chose?
