Is running long distances at the age of 15 harmful to growth?

Question

I can't remember where I heard it but it was something along the lines of if you run too much while you're still in puberty, it could effect growth and proper bone development. I usually run a mile every other day and will do more as the weather gets nicer.

Answer 1

I've heard that too, but I know some girls who ran cross country their freshman year when they were 15 and all of them were just fine.

Answer 2

no...
