This equates to around 23.4 miles per hour during the length of the race. During the sprint, Bolt hit an incredible 40 feet per second for a brief period of time (27.51 mph). This is also considered human speed limit.
Bolt's fastest 100-meter dash time was 9.76 seconds, set while winning the gold medal at the 2008 Beijing Olympics. That's nearly three full seconds faster than anyone else has ever gone before or since. He averaged about one foot per second over that distance. In fact, no one has ever beaten Bolt by more than two seconds in the 100-meter race—and none have even come close. His current career best is 9.58 seconds, set earlier this year.
Bolt first broke the sound barrier while racing against American Leroy Ellis in Tokyo in 1996. The Japanese national anthem was played when he crossed the line ahead of Ellis by several seconds. Since then, only one other man has managed to break the sound barrier on foot: American Bobby Lashley. He did it at the 2007 World Championships in Osaka, Japan, with a time of 4.56 seconds.
Lashley is also the only other person to have broken the four-minute mark in the 100-meter dash. He did so in 2009.
Usain Bolt's 100-meter sprint in London was the fastest in Olympic history, running more than 23 miles per hour for 9.63 seconds. Marathon runners reach half of Bolt's pace after running for two hours. A moderate walker can cover one mile in about four minutes. So at a brisk pace, a person could travel nearly a football field in about six seconds.
Olympic athletes are not the only ones who play sports at high speeds. Professional baseball players hit 95 mph pitches and make over 200 trips around the bases in an entire game. In NBA basketball, players move at more than twice the speed of sprinters from 100 meters to 500 meters. And in NFL football, quarterbacks complete passes at more than 10 yards per second.
Athletes perform at high speeds because it requires great concentration. They must avoid obstacles on the track or field and be able to make quick decisions if they want to win. Sports psychologists say that exercising at high speeds keeps our brains active and helps us maintain our mental health.
In addition to professional athletes, regular people exercise at high speeds every time they go for a drive in a car or take part in a race.
The fastest man on earth runs with a speed equivalent to approximately 12 miles per hour. That's faster than most people walk!
Improved training and practices Sprinting velocity is a function of step length and step frequency. Usain Bolt ran at 12.4 m/s in his quickest phase of his world record performance in Berlin in 2009. To run 100m in under nine seconds, a human's maximum velocity would need to be around 13.2m/s. No one has ever done this as no one else has even come close.
The current world record is 9.58 seconds, set by American Justin Gatlin in Birmingham, Alabama, on September 2, 2019. If you subtract 0.04 seconds for each of the three allowed head-to-head comparisons with Gatlin, then the fastest possible time is 9.64 seconds. The average speed over 100m is 1020.1 ft/min (100 meters per minute). This means that to run 100 meters in under nine seconds, you must walk about 1.5 miles (2.5 km) per second.
Gatlin's victory was controversial because multiple athletes were prevented from competing due to doping violations. However, even after these disqualifications, the remaining field was still faster than the previous record holder, American Michael Johnson, who ran 9.72 seconds in 1988.
It may seem hard to believe but humans have never been able to run 100 meters in under 10 seconds. The closest anyone has come is 9.93 seconds, which is more than two full seconds slower than the fastest man in history.
This, however, does not tell us who ran the quickest, only who had the best average speed over that distance. If you average the current world 100 m record (Usain Bolt's 9.58 s), you get 10.44 meters per second (23.35 miles per hour, 37.58 kilometers per hour). That's fast! But it's not the fastest anyone has ever gone.
The current men's Olympic marathon record is 2:16:59 set by Haile Gebrselassie in Rio de Janeiro in 2016. That's about 27 minutes per mile (43 km per hour), which is extremely fast. But it wasn't recorded when the race began, so we can't say who runs the fastest marathon now.
The fastest human has yet to be determined, but there are strong indications that women are faster than men over the course of a marathon. There are two main reasons why this might be true:
Women have longer legs, on average. So if they start out running at the same pace as men, they'll cover more distance over the same amount of time. This is supported by research showing that women use less oxygen during exercise than men do. The only way to prove whether or not women are actually faster than men is with a direct comparison between them; however, since such a study has never been done, this conclusion is based on evidence rather than actual data.
Some women run faster than others.
So far, the quickest time has been around 27 1/2 miles per hour, which sprinter Usain Bolt achieved (briefly) shortly after the midway of his world-record 100-meter dash in 2009. The strength of our bones and tendons most likely does not enforce this speed restriction. Humans can easily accelerate to dangerous levels if we want to go faster than this.
In fact, scientists have proven that even sprinters like Bolt can be driven to extremes of speed if necessary. In 2004, researchers from McMaster University in Hamilton, Ontario, monitored Bolt as he ran several hundred meters at a time on a special treadmill. They found that despite being a skilled runner, Bolt could only manage a top speed of 20.5 miles per hour - about equal to walking pace - for about two minutes before he started to struggle.
This is because muscles need time to recover between uses so they don't get injured. If we try to run at a high speed for a long period then the muscles will be stressed beyond their limit, which can lead to injury.
In conclusion, humans are limited by biology when it comes to speed. We can run very quickly for a few minutes if necessary but cannot maintain this level of speed for long periods. This is why athletes like Bolt who are highly trained can run so fast; they have overcome this natural limitation through practice.
