I don't know what your country's equivalent of "Little Athletics" is, but the first thing they seem to teach young kids here is to "run quietly". Kids (and us too) instinctively know how to do that: land on the front of your foot, and you do that by not striding forward too far. This is the most efficient running action.

It's the most efficient running action for sprinting or middle distance, for sure. But kids aren't taught long-distance road running. (They don't have the stamina, and it would bore them to tears.) As a child or teenager you're unlikely to run more than 1500m on the track or 2M cross-country.

Not sure if that's relevant or not.
