Elephants never leave the ground; this is a fast walk, not a run. MEASURED by photosensor timing and video over 188 trials, but in ASIAN elephants. The compilations disagree -- 34.0 (Bejan & Marden 2006) and 35.0 km/h (Garland 1983) -- and Hutchinson has publicly attributed those to speedometer-based anecdote. A measurement of the wrong species beats an estimate of the right one, but this needs a reviewer's decision.
