Kim, I can absolutely relate to everything you wrote. My son is so competitive, and he's also very private about his running.It's not so much his coach that pushes him as his fellow runners, and himself. He's missed most of spring track season with injuries and it seems he gets a different one every season. He's a junior this year and wants to run in college on certain teams and that stress doesn't help.
He doesn't like to tell me when he's hurt. He thinks I'll make him stop, when most times if he caught the injury early enough he would just have to ease up for a week or so.
My son eats a bad diet, with very little protein unless you count pizza or cheese steaks. He majors in pasta during race season, but at least he puts some cheese on it. Runners deal with pain all the time. And there are times when it's appropriate to run with some pain. But sometimes you have to stop.
I walk the line between wanting him to want to push himself and do his best, and not wanting him to do too much and get hurt. Whatever I say it's often the wrong thing to my son. After a bad race if I encourage him he hates it. If I get happy for him when he's had a good race, not often a good thing either.
Normally the diet isn't much of a concern with boys. If a girl gets a second stress fracture on the running team they automatically run her blood. They could be anaemic and not be getting enough calcium. Male runners are also sometimes anemic especially when they put in high miles and eat poorly. It's most likely nothing, but they want to look at it closer. Talked to coach, he sent me to dr.
