Yes, exactly. If you're a sprinter in the range of 10.5-11.0 sec. at
a hundred (average speed of 32-35 km/h), youre maximum speed should
be around "forty". Unofficialy I've clocked 0.89 s. at one 10 m. leg
of a hundred. Calculate for yourself. ;o)

I visited Wienna 5 years ago, and I walked exactly that fast. ;o)

Long but thick. Also, animal that heavy needed to keep stability,
which is harder if you're moving fast.

BTW, the study of elephant running speed seems incorrect to me. I
mean, the value of 25 km/h is much less, than many african (if it was
really _L. africana_ not _E. maximus_) hunters would give you. Famous
Czech traveler, J. Wagner himself clocked one old female running at
over 40 km/h when attacking a jeep. And it was old and big
individual, very likely over 5 tons of weigh.
