Not enough info. What do you mean by "college training"? HIgh mileage, high intensity, both? Is she the only one on the team injured? Are all the other kids able to handle the training? Are the freshmen newbies doing the same workouts and mileage as the seniors who have been running for 4 years?
There are some coaches, usually of large school, historically successful programs, who just get a bunch of kids out, run them hard, and let the weak fall by the wayside. They can do that because they have numbers. Is that what is going on?
Good cross country coaches modify training based on the background of the kid, prior sports activities, etc. They don't just throw all the kids into the same training plan. Our incoming freshmen start in June doing run-walk at first. Now, those same freshmen kids, 8 months later, are running anywhere between 25-50 miles per week. That is quite a range. But some of them had great sports background, or even running background, and others were couch potatoes and not athletically gifted at all.
Having said that, I have coached a few kids who get injured doing next to no running. Most of these kids have little sports background, are weak, did not do any summer training, might be overweight, don't get enough sleep, have poor running mechanics...lots of factors add up to injury. It's still my job to work with these kids and bring them along slowly, but if you have a large team, as a coach, you often have to ask yourself whether your time is better spent working with your healthy athletes or sitting in the weight room watching the injured ones do the elliptical and a lot of hip and glute work.
If your kid is easily injured better make sure your kid is doing the extra work she needs to stay healthy. Does she get enough sleep? Does she eat healthy? Is she taking Vitamin D? Often, it can't all happen at practice, some of it has to be done at home on their own time for the kids who are really injury prone.
