Without any specific injury or evidence of ill health, and if she's in good shape and enjoys running, female of this age are perfectly capable of running long distances.
It is fine! It's actually great for her to love running, that means she is in fit. As long as she keeps a safe distace and stays out of trouble, it should be fine,
