Have come across it in every sprint training group I've been in, and have seen it with middle distance runners too. People who train and train, yet NEVER actually enter a race. Why is this? Is it fear? Is it ego of not wanting to run a time slower than people think you can run? What is it?
I simply could not be motivated to train 5 days a week if I was not going to race. I just do not understand the logic behind it.
