Yeah, but the marathon wasn't established until 1896 and so is of
little importance to human evolutionary history.

The point is (or ought to be) that sweating
causes the loss of body salts. Sweating
as a common response to exercise or heat
could only have evolved in a species
which was able to replace those lost salts
in a fast and convenient manner.

Ergo: humans evolved in a habitat close
to the sea.

There are no other hominid species extant,
so it is to be presumed that they were
all competitive to humans or to human
ancestors. All must have occupied a
habitat close to the sea.
