[4] [5] (Bolt's average speed over the course of this race was 37.578 km/h or 23.35 mph.) [6] Compared to quadrupedal animals, humans are exceptionally capable of endurance, but incapable of great speed. [7]
A human traveling on a bicycle at 16–24 km/h (10–15 mph), using only the power required to walk, is the most energy-efficient means of human transport generally available. [5] Air drag, which increases with the square of speed, requires increasingly higher power outputs relative to speed.
The preferred walking speed is the speed at which humans or animals choose to walk. Many people tend to walk at about 1.42 metres per second (5.1 km/h; 3.2 mph; 4.7 ft/s). Many people tend to walk at about 1.42 metres per second (5.1 km/h; 3.2 mph; 4.7 ft/s).
On land, the speed record registered by a rider on a 200-meter flying start speed trial was 133.28 km/h (82.82 mph) by the Canadian Sam Whittingham riding the Varna Tempest, a streamliner recumbent bicycle in 2009, [19] at Battle Mountain, Nevada. His record has been surpassed by 0.5 km/h by Sebastiaan Bowier of the Netherlands in 2013 setting ...
Pronghorns can reach a top speed of 60 mph (97 km/h) in good conditions, and a top speed of 50 mph (80 km/h) normally. [60] They can reach speeds of 72 km/h (45 mph) in a 2–3 km course. [ 63 ] Estimated by observing the odometer when the animal ran at its maximum speed, alongside a vehicle.
