"If I don't have a sense everything is basically full steam, I'm not going to run,"
Bode Miller, US Ski Team January 2nd, 2015 AP article published on ESPN.
These are the words of a champion. Individuals who are the very best will not compete unless they believe they are capable of winning. "Full steam" for Bode means being able to compete at the level which makes winning possible.
This is a strong message for any junior skier or any other athlete who thinks that competing through injury is the way to winning gold medals. While champions may certainly compete with aches and pains, they will not enter the starting gate unless they know they can go 100%, which at Bode's level means competing to win.
The take home message for any injured junior skier or any other athlete, unless you can get into the starting gate knowing that you can give 100%, you are not yet ready for competition. You will not get your desired result and more importantly you run the added risk of further injury.
