She's too young.
I've run with all my dogs, and Luc has done 40k runs, 60k non-stop hikes, 80k in two days backpacking. But he was fully grown.
A GSD's growth plates etc won't be closed until around 18 months old. They're big dogs. You need to wait until her joints are physically mature or you risk causing damage.
Once she is old enough, if she walks regularly, starting her slowly with running and building up to longer distances should be fine. Not yet though.
