Wait, do elephants actually run?
Strictly speaking, no, not in the way a cheetah or a horse runs. A true "run" requires a moment where every foot leaves the ground at once. Elephants never do that. Instead, they use a special extra-fast walk called an amble, keeping at least one foot on the ground at all times.
But don't let the technicality fool you. At full amble, an elephant can hit around 25 km/h (15–16 mph), which is faster than most people can sprint. It's less "running" and more "the world's most efficient power-walk."
