It's not an easy decision to step back from the start line. I won't lie - I wrangled with feelings of failure and shame. Feelings of frustration that this was yet another race that I wasn't going to run because I was injured. But those feelings are all superficial. Those are the feelings controlled by the dark side of your brain - the side that doesn't focus on your health or integrity. Those are the feelings you have to stand up to and say, "Not today, Satan."
