The fastest among us can sprint 100m at a speed of 15.9 mph, or between 13-14 seconds. The Olympic qualifying time for London 2012 was 10.18 seconds in the men’s race and 11.29 seconds for women.
Jamaican sprinter Usain Bolt holds the current world record: a sprightly 9.58 seconds.
If he covered the 100m in 9.58 seconds, that’s a speed of 100/9.58 = 10.44 m/s (which is 23.35 mph ), right? 23.35 mph is certainly Usain’s average speed over the race, but as you can appreciate, he does not run at this rate for the entire race. Usain starts at rest, so he has to accelerate to build up his speed.
According to Fox News, humans—who top out at roughly 23 mph —may one day be able to reach phenomenal speeds of up to 40 miles per hour. That study showed that speed is based more on contracting muscle fibers than it is negated by sheer force of running.
Limits of speed The record was 44.72 km/h (27.78 mph ), measured between meter 60 and meter 80 of the 100 meters sprint of the World Championships in Berlin on 16 August 2009 by Usain Bolt. (Bolt’s average speed over the course of this race was 37.58 km/h or 23.35 mph.)
Do Sprinters breathe when sprinting? The answer is, of course, yes. There are a few pointers on when to breathe (inhale) and when to simply exhale.
United States sprinter Justin Gatlin recently ran the 100 metres in 9.45 seconds on Japanese television show Kasupe!, topping Usain Bolt’s world-record mark.
In 2009 Jamaican sprinter Usain Bolt set the world record in the 100-meter sprint at 9.58 seconds. For those of us more accustomed to sitting than sprinting, to translate this feat into terms of speed is to simply underscore the stunning nature of Bolt’s performance.
Originally Answered: Can you run 100m under 9 seconds? Considering that the World Record for the 100 meter dash is 9.58, set by Usain Bolt in 2009, nobody can do that.
Cristiano Ronaldo is faster than Usain Bolt at the moment, according to the fastest man in the world. Ronaldo has also received praise for his speed in the past by Spanish professional sprinter Angel David Rodriguez.
Lyles, running in Florida, completed the race at the Inspiration Games in an eye-watering 18.90 seconds – which would have smashed Usain Bolt’s world record of 19.19 seconds and his own personal best time of 19.50. Swiss television said he had only run 185 metres.
Yup, reaching a peak speed of up to 21 mph is ofcourse deadly quick. It also means that your average speed would be somewhere between 18–19 mph. In terms of racing the 100metre dash, that sort of speed would translate into a time between 11.65sec and 11.88sec (depending on how long you hold the top speed.
When we applied the same model to mile runners, we calculated the world record should be down to 3:33.29 in 2028 and to 3:29.84 in 2040. A sub-three- minute mile, though? That is scientifically and physiologically impossible.
This year’s Olympic Games means another dose of track superstar, Usain Bolt. Bolt, an Olympic multi-medalist, is the fastest man ever recorded. The Jamaican sprinter was best known for his performance in the 2008 Summer Olympics in Beijing, where he sprinted 100 meters in a 9.58 seconds. That’s about 23 miles per hour.
