Should high schoolers train "harder" than college runners? In my experience high schoolers do more workouts, and do them at closer to race effort, although that could just be anecdotal. Is this just because a lot of high school coaches don't know what they're doing? Or is there a phsiological difference that makes harder training better in the high school age range? There must be a thread about this somewhere but I haven't been able to turn anything up.
I think I've read an argument on here that high schoolers recover faster and so should work out harder and more frequently, but does anyone have evidence to support that or an explanation of why it is? And if this is true, is it definitely caused by age or might college runners only have lower recovery because they're already burnt out from high school?
