I agree with the first scenario, but the 2nd scenario just wouldn't happen
No one gets through elementary school without figuring out if they are fast at sprinting
I am not sure where you guys are growing up where people don't figure out they are sprinters until someone trains them as sprinters
This argument has nothing to do with the point. We are discussing how to detect whether someone is a "sprint type" or a "distance type". Do most kids find out their sprint abilities in elementary? Yes, of course. Does being good at sprinting mean someone is more of a sprint type? No. Does being bad at sprinting mean someone is more of a distance type? No. This argument adds nothing to the thread.
As a coach, I have my athletes run 3 time trials during the early season: 100m, 400m, and 1600m. I also pay close attention to their natural form and take their body types, personal preferences, and team needs into consideration. From there, I assign each kid to the group that I feel is best for them (sprint, MD, or distance). Most of the time, I get it right. Occasionally, I switch kids into different groups after I watch them race/mature throughout the season.
