Except that humans are such piss-poor sprinters. Hardly any terrestrial
animal in the world is as slow as we are. Kangaroos on the other hand
are fast.

This is just what the article argues. We are slow runners, not fast.
For myself, I jog almost everywhere. I find walking boring and tiring,
so I only do it when with people who don't run.

In northern europeans. Most of the rest of the world is slim and
small-boned in comparison. Different modern groups have different
recent evolutionary trends.

But almost anyone of any body type can train and run a marathon, the
kind of running this article discusses. Remember that we moderns are so
weak and flabby, most of us, that we can't do much of anything our
ancestors could. Humans can out-jog almost every other kind of animal
except horses, dogs and a few others.
