Humans spontaneously switch from a walk to a run as speed increases. In humans, the preferred transition speed from walking to running typically occurs around 2.0 m/s (7.2 km/h; 4.5 mph), although slight differences have been shown based on testing methodology. [1] [2] [3] [4]
The record is 44.72 km/h (27.78 mph), measured between meter 60 and meter 80 of the 100 meters sprint at the 2009 World Championships in Athletics by Usain Bolt. [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]
The world record for men is 12:35.36 (an average of 23.83 km/h) by Joshua Cheptegei of Uganda in Monaco set on 14 August 2020; The world record for women is 14:00.21 (an average of 21.43 km/h) by Gudaf Tsegay of Ethiopia in Oregon, United States set on 17 September 2023; The 10,000 metres is the longest standard track event.
Equivalent to an average ground speed of 10.45 m/s, 37.63 km/h, or 23.38 mph. He ran the last 100 m in 8.70, the fastest ever recorded time over a 100 m distance. This would equal an average speed of 11.49 m/s, 41.38 km/h, or 25.71 mph. 300 metres in 30.97 seconds 27 May 2010 in the Golden Spike Ostrava in Ostrava, Czech Republic: NR
Speed limit sign in the Republic of Ireland, using "km/h.". The SI representations, classified as symbols, are "km/h", "km h −1" and "km·h −1".Several other abbreviations of "kilometres per hour" have been used since the term was introduced and many are still in use today; for example, dictionaries list "kph", [3] [4] [5] "kmph" and "km/hr" [6] as English abbreviations.
The fastest human footspeed on record is 44.7 km/h (12.4 m/s; 27.8 mph), seen during a 100-meter sprint (average speed between the 60th and the 80th meter) by Usain Bolt. [ 86 ] Speed over increasing distance based on world record times
