tell her not to give up on her dream. my daughter couldn't pass the run test either and then i told her to get with someone who has passed the test and ask them to run the test with her. that way she could stay at their pace. it worked and she passed and was able to continue on and graduate. so in 6 months from now if she is having trouble with the run test have her try running with someone that has already passed.
but most of all don't give up on your dream of being a sailor!!
