Whenever a young kid is running a lot of miles (and possibly being trained by a parent), on here and on other running forums there are dire prediction of burnout, injury, and truncated careers. I don't doubt it happens and we all know of some notable cases.
On the other hand, I've seen reputable articles which try to explain the African running dominance, and they invariably reference all the miles the African kids do while young, such as running to school both ways.
So what's the difference? That one training is informal and the other is formal?
I ask because I have a middle schooler whose track club coaches think has some talent. (Her older sister is running for a top Div. 1 program, so this is possible). She ran xc with school and won a lot of races including the championship. Now she's doing club track, with team practices 2x per week, and races on Sat./Sun. On 4 of the other days, she runs on her own for 30-40 min. and does core like sit-ups and push-ups. So she averages 2 days off. Sometimes 1, sometimes 3, but always at least 1. That seems reasonable to me for a girl her age.
But here's the thing--at youth meets she is getting beaten, which I don't mind. But the gap by which she is getting beaten is pretty scary! I have to ask myself what on earth are these other little kids doing, not to mention when do they have time to do it, what with school, and homework, etc.? There are twelve year old girls running 2:20 800's and 5:30 1600's already at the start of the indoor season. At the spring national meet, the winning time for the youth girls 800 was 2:10. That's insane. You can chalk up a kid like that as being a special talent and future Olympian, but even our club coaches are puzzled about the number of young girls who are super fast. Yeah, I know puberty messes with girls some, but still!
Then on the high school level, I've noticed that in our state that the younger girls are getting faster and faster. Most of the top girls are getting privately trained and some are running a heck of a lot of miles too. The top girl when my older daughter ran was putting in 70 miles per week over the summer. So what's a kid to do? You have to partially keep up with these privately trained go-getters or else you don't run fast enough or win enough to get noticed by a college. But if you do, then you risk ending up injured and burnt out.
Enlighten me, o wise ones.
