There had only been a few times during the run that I let go and allowed myself to run all out, for fear of injury. On Day Thirteen that was exactly what had happened. It nearly derailed me. That day was a distant memory. There was not a sore or tight spot anywhere in me. I allowed my pace to quicken and my stride to go. If you are a runner you know this space. It is that last half mile of your first 5k or 10k. It is that last mile of your first marathon, when only an hour before you wondered how you could possibly finish. Yet there you were, running full out. Unstoppable!
