I don’t think she should give up but I’ve noticed in some of her photos she does look a bit gaunt. She also looks like she is at race weight all the time. Maybe try to put on a few pounds during her training. I really hope she does not have an eating disorder. That would certainly reck havoc with her racing and training. You don’t have to be rail thin to have an eating disorder. Bulimia is equally as dangerous as Anorexia.
