99% of high school coaches are compétent enough not to derail à runner with that kind of ability. Just about every coach will schedule 1-2 easy days after each hard workout and recommend à long run over the weekend. I rarely heard stories of kids being pushed too hard.
Pro runners are pros because of talent and not because of who had coached them in H.S.
I think you underestimate how a bad coach can screw a kid up either by over-racing or injuring them or just sucking the fun out of the sport.
A friend has a great line: have as a goal never to be a kid's last coach. That means the kid enjoys the experience enough to continue the sport.
