Go to a cross country meet in September-big invitational=5K In suburban Denver, there will be a dozen runners clustered around 16 minutes-maybe 25 under 17 minutes. 50 under 18 minutes-100 between 18 and 20 and 200 over 20 minutes.
Those sub 17 minute kids are your 5 minute milers. Those 18 minute kids are 5:30s.
Extrapolate throughout the state-there are a couple hundred kids-maybe.. 50 states-some are bigger than Colorado, some are smaller but my method give 1000 nationwide. Probably a little low, but not by a factor of 10. Split the difference-5000.
My high school PR-4:56. In Gunnison, CO at 7500 feet.
Your conversion of an xc 5k to a track mile is horribly off. For a faster xc course with a couple decent hills 4:30=16:25, 5:00=18:00, 5:30=19:45. And your way of figuring out how many sub 5 milers there are is way off. Kids who go sub 18:30 are generally capable of going sub 5 in track- in fact, I have yet to meet a high school runner who runs year round who has gone sub 18 that failed to break 5 later in their high school career. I am in a solid running area, it generally takes sub 4:15 or even faster to win states and in my COUNTY that has 15-30 schools, there are a couple hundred guys that go sub 5 every year. In my state there are probably a couple thousand and I live in a medium sized state. So it would definitely be up in the 30-40 thousand range if you factor in the states that are horrible.
