Gale,
First, the facts... The coach should not be allowing her to run, nor should the teams trainer. If she has permanent injuries like you described I can't imagine her being cleared to run. Does the schools athletic director know of the situation? You NEED to contact them. Anytime there was an injury the trainer was the first one called. I can't imagine all three of these people saying "oh no shes fine, let her run. Being able to walk when you're 30 is overrated anyways!" And if they are, then shame on them for not doing their job.
Secondly, my blunt opinion... Your husband is being ridiculous. If he wants to relive his glory days then tell him to take up jogging or something. Girls at that age have hormones going so haywire that of course shes going to want to please and make her daddy proud. Daddy needs to be a man and be proud of his daughter regardless of whether or not she follows in his footsteps. I'm not a father but I couldn't imagine pushing my child to that extent. Its one thing if the kid scrapes their knee and you tell them to get back on the bike. Its a whole different story if they have a gaping, gushing wound and you say "rub some dirt in it". Your husband is being downright selfish, plain and simple.
If you ever need to rant anymore, feel free to PM me. You always seem so nice, seeing you upset is no fun
