according to the fitness standards i mentioned and assuming normal distribution, about 1.5% of all males age 13-17 can run sub 5:00 mile. according to the 2000 census, there are about 31.5million males age 15-19 in the US, so assume about the same number of males age 13-17. that gives in the neighborhood of 400,000-500,000 high schoolers alone capable of sub 5.
of course, i know the distribution is not actually normal because the same calculations would predict 30,000 high schoolers capable of sub 4:00.
Assuming you're serious and not just putting us on, there are two observations about this.
1) That's the number CAPABLE of doing it, not the number who actually do. For example, many large inner-city high schools suck at XC and have little if any depth at distance events in track. So they produce few sub-5:00 milers. But the school is full of kids CAPABLE of running sub-5:00 -- probably a dozen or more in the basketball program, and every 51-second quarter-miler they've got. And that's just the kids who are in a sports program instead of in trouble or working a job to help pay the rent.
2) Calculations that predict 30,000 high schoolers capable of sub-4:00 strain credibility. Certainly we're losing large numbers of talented runners to other pursuits, but 30,000? That's about 30 times the number of people who have ever done it! There are about 20,000 high schools in this country that have sports programs. There is no way on God's green earth that the average HS has a sub-4:00 kid in it.
