While this poster has good intentions, I will point out some flaws in the reasoning. I edited the post down to point out:
First of the quoted paragraphs, last sentence. A high school coach NOT agreeing to coach in exchange for money removes no opportunity for any kid interested in distance running. I imagine it's hard for sprinters, jumpers, or throwers to find opportunities to compete. In fact, when I'm be running with the guys in high school, we would speculate aloud about what we'd do if our best events were shorter. But since we were running 10k and up, there was no problem. Races were constantly being held. These days, 5k is more popular than it was then, so the only scenario in which the existence of a school-paid coach helps is if you're interested in mid-D or sprints. Or field events, which the OP isn't.
Next paragraph. The last bit about working with the coach, and admittedly that limitations exist as to how effective that can be is not the greatest advice. If you discuss nothing with the coach and don't train according to his/her inept orders, you are not limited by said ineptitude. This really does work. If you avoid the coach, easy to do by not showing up for a practice - ever - they simply don't affect your training. I never showed up, and I was the best distance runner in the school district. This wasn't in Iten, so that may not be saying much, but it's worth pointing out that I wasn't the slowest one at school.
The final sentence is misleading. True, these clowns scrounging for a few grand with some part-time after-school job will probably NOT change and suddenly become Canova, or even JS, no kid is stuck on the team. Conceivably some exceptions exist, i.e., parents require participating in a school-sanctioned sport, court order after getting in trouble, it's a graduation requirement, etc. Without any unusual circumstance, however, I can assure you that nothing happens if you simply never sign up. No consequences exist. There IS another way: run exactly the way you see fit. Use this site to help you.
