Their little legs must be so tired

I can't tell if this is serious or ironic.

Do kids still play running games at school? Football--uh, soccer? Tag? British bulldog[1]?

A half-hour walk each way should be negligible.

Its a 15 minute walk there, 15 minute walk back. But I make the trip twice... they only do it once. So they get 15 minutes at a time.

Half and half, but really - it depends how old the kids are. 110 steps/min might be 180 steps/min for a smaller kid.

Also, kids frequently play by sprinting and then relaxing, and then sprinting, relaxing, etc. It's only boring adults who do steady state cardio like a long walk.

As a child I would want to go somewhere that was often 2 miles away and for whatever reason a bicycle wasn't used. I didn't consider it cardio I considered getting somewhere.

That's an interesting observation, I'd never noticed that but you're right. There was always something uncanny to me about high school teams for cross-country running but I could never put my finger on it.

That’s partially the competitive aspect as well. High school is peak “everyone can find something to compete in” for a lot of communities. Before that sports are usually more about play and afterwards tend more to recreation or exercise. Again, just generalities.

British Bulldog is still played all the way down to kindergarten in Scandinavia. It's called "hawks and doves" or "all my children come home".

They must be joking. There's cardio heavy trainings that kids do for hour and half and I did myself when I was younger...

Soccer, karate, judo, whatever.

You wish! 7 to 7, AM to PM non stop running activity. They'll be doing cardio anyway, whether we're walking to school or not.

And strong
