How Fast Can Humans Run?

Women running fast on a track

The average human walking speed is in the neighborhood of 3 mph (4.8 km/h). How fast do you think you could run at a full sprint? 10 mph? 15 mph? What speed could you average over 26.2 miles?

Below, I have taken several men's and women's world records and calculated the runners' average speed. Usain Bolt has averaged over 23 miles per hour in both the 100 and 200 meter events.

It's interesting to note that the 60 meter race has a slower average speed for both men and women than the 100 meter race. This must be because accelerating at the start of a race takes some time.

These world records were last updated on May 5, 2010.

    chart shows average speed for each..

    what would top or final speed, for instance, in the 100m dash?
    thx

    John –

    I’ve heard that the peak speed for the best 100-meter sprinters is in the neighborhood of 27-30 mph. This will typically be achieved about 2/3 of the way into the race, then the speeds will drop again slightly. Even the best athletes can’t maintain that kind of speed for any distance.

    Often when you’re watching the end of a race it will look like one runner surges out in front of another runner, but in fact both are likely to be slowing down. It’s just that one of them is slowing down faster.

    I was watching this show that answers questions that most men want to know. One of them was how fast can you go for your muscles to fall off. they said it was about 26.5 mph. Is that true?

    With a bunch of my friends and one more crazier than the others we made him run at a speed of 35 mph. How we did it? We accelerated a car to that speed, then he jumped out of the backdoor and continued running. Ofcourse he didnt maintain that speed, but for a brief amount of time he did run 35 mph… I tried that too, but I fell down at a measly speed of 20 mph. My friend is the son of priest so he might have had some “outside” help :)

    When I was 13 I did the 100m in just over 17 seconds so about 13 MPH/21 KPH. I have not done it since then and I’m 17 now. But I know I am a lot faster now so probably under 14 seconds is my time. My standing vertical is 21 Inch and average male is 19.5. I hear this is connected to sprint speed but who knows? And I’m 5’11″ and weigh 143 and when I was 13 I was way shorter than average but I had a big growth spurt at 15 so my legs are way longer now :D

    Fastest I ever ran was about 20 miles per hour. Though you have to take into consideration that I had just hiked 10 miles up a mountain, and on the way down I ran the last 3 miles. But usually I can hit a dead sprint at about 15-17 miles per hour on flat ground. I was 16 at the time but I’m not even close to as fast as my dad.

    interesting during the atlanta games we were getting radar gun read outs of the mens long jump top speed on the run way on our australian telecast… Carl Lewis was hitting over 43kph he was actually faster in a 100m and his relay final dash beleive it or not he would actually run away from Bolt! not by much but his relay splits are actually quicker due to not needing to get up out of the blocks he actually ran away by 5mtres on D. Bailey at the texas relays when bailey was at the peak of his powers after the 96 games, of coures 10metres from thew line he grabbed his leg an claimed cramp LOL ps im not from the USA I just like sprinting. ps bolts top speed is the same as lewis long jump topspeed he just accelerates so much quicker than lewis… interesting

    Hi, I am doing a research on the subject of Sports Science and found your site.
    I am curious on how you get his results. I check the two values that I am most interest and found that they are not consistent.
    I wonder how is possible that Usain Bolt ran 100 m faster that Florence Griffith Joyner but his average speed is lower? That´s quite a feat!

    Event Record- Athlete – mph – ft/s – km/h – m/s
    100 m – 9.58 s – Usain Bolt – 23.35 – 34.25 – 37.58 – 10.44
    100 m – 10.49 s – Florence Griffith Joyner – 21.32 – 31.27 – 34.31 – 9.53

    Hello, My name is Forrest Rogers and I am 18 years old, 5’10″ and 160 pounds I mountain bike and hike weekly and on the off days I run on the treadmill. So after reading the material on this site I decided to run on the treadmill and checked my speed ( its the type of treadmill that has a read out for your top speed ) I was amazed to find out I can sprint at a top speed of 25 MPH. Also I belive anyone who has said they have ran over 30MPH is full of lies and should not be trusted the only way a person could move over that mark is by mechanical help. Also as a side note a 2 year old could not search the web and fully understand what people are saying therefor the people who said they are 2 years old are are not telling the truth. – Thanks for your time ^_^

    Some funny comments here. These are average speeds. One has to consider the acceleration time. When you sprint you don’t reach top speed immediately. The closest to top speed you will get is generally over 200m. Bolt has reached a top speed of over 28mph.

    To the kids saying they run 30+ MPH…just be quiet. Nobody is physically grown enough to run that fast at the ages I’m seeing (Orpheus, you’re only fooling yourself. If you run that fast then why have I never heard of you?)
    The fastest I’ve run…19 MPH, roughly. Not amazing, but I’m proud of it, and I don’t try to embellish it with an extra 10 MPH.
    Usain Bolt’s crazy fast. They clocked him at 27.45 MPH at the 65 meter mark…faster than a car in the neighborhood!

    Me and my mates tried downhill training for our 100m once and I got upto 25mph over a 20m section, it really helped extend the top speeds we ran at.
    I also tried some experimental training and it worked to take almost a second off the 100m times were were running.
    I’m going to tart training again soon, hope to get back to where I was.

    Agree with a previous poster about endurance…it boggles my mind that someone can keep up a 13 mph pace for 2+ hrs…just think about that. For most people, you’d have to give them CPR after 10 mins…that is if they could even run that fast to begin with! Incredible

    I’m 13 years old and my speed was measured and I reached a speed of 19mph. Also a human can NOT run at 40-45 mph because then he would be faster than some of the fastest animals and that is not true.

    July 12, 2012

    if we look at the fastest 10 meter increments in a 100m race , Usain Bolt has run 10 meters in 0.83 second. Several top guys including young Frenchman Christophe Lemaitre are very close to this speed too. It works out just over 43 kph or around 27 mph. That is as fast as anyone has yet run.

    I believe I have an article pertaining to Usain Bolt. Apparently not even he can run at 30mph, but I would like to see a human run even faster than that. How about, for example, a man running at 40mph or even 60mph like Steve Austin? Olympic records seem to have been broken over the years, but it seems to be believed that there is a limit as to how much a human’s performance can improve. Powerbocking seems to be a way of increasing a man’s running speed so I wonder how fast Usain Bolt would be able to run if HE was powerbocking. At the moment I don’t think of even him as superhuman, eventhough he seems to be the world’s fastest man. Hence I would like to see superhuman achievements in the Olympics and World Championships, even if it means using performance enhancing drugs. After all, I think one purpose of those sporting events should be to see what humans can achieve. I therefore do not think such drugs should be forbidden.

    Believe it or not.. some of the light body gung-fu masters in China can actually catch horses. In fact some of them were specifically hired to catch horses that had escaped. They practiced the art of running fast and jumping high. It is a very little known, multi stage training that involves running in a very specific manner, special weight training, breathing exercises, chi-gung and meditation along with several special secret speed training techniques.

    I used to practice parts of the training myself and in just a few months I went from being able to run 18mph to over 22mph and that was still not full speed. The initial acceleration made me feel like I had a rocket pack on as well. Just from that alone I could clearly see that speeds such as those reported in the Shaolin stories could well be attained after many years of dedicated training.

    Same goes for high jumping as well. I’m not even going to tell you the Shaolin record as most will think I’m lying or crazy.. but it’s well beyond the mere 2.50 meters of world record holder, by several times at least. That’s because the training regimen is considered nothing short of insane or impossible. Basically no one today trains that way anymore, so most don’t really know what the body is truly capable of when you combine the internal and external, along with special training methods, different theory other than jump muscular strength and you attain quite different levels of power, strength and speed than what most consider to even be possible. Even in the old days such knowledge in China was never well known, as there were and still are prized secrets, and certain aspects of this knowledge are virtually lost today.

    In answer to Jans question of March 6 2011 to convert from 100M speed in seconds to Miles Per Hour all you have to do is (if I have my math right) multiply by 2.44 and so her speed is apparently 26.6MPH.

    Which is somewhat better than my current 9.45MPH.

    On another note my personal best when I was about 13 was 35.1MPH according to my treadmill. Interestingly I lived at a number 35 at the time, and oddly I am missing most of year nine from both my attendance record and my school books.

    It seems my math was wrong on my last comment, I’ve just realised that you have to divide 100M by the time and then multiply by 2.44. And so I’m sure everyone can do the math on that one.

    I am 73 and still running strong. I can run the 100M in 12.5 seconds. I have a slow start, though, so I think I’m pretty quick.
    Also, I can high jump 6’5″ (I’m 6’2″). I weigh 200 lbs and have 5.2% body fat. I can also curl 110 lbs. each arm and I can squat 275 lbs.
    I also can swim a 100M in 1:01.06.
    I also have no left hand (when I curl I just hang the bar from a strap on my forearm). I do have to wear a small paddle on my arm when I swim for competition.
    Last year I jumped out of an airplane in a low flight pattern (approx. 50-60 ft off the surface of the water) without a parachute or life-vest. The year before, bit the head off a live rattlesnake and skinned it with my teeth (but I got salmonella).
    20 years ago when I was stronger and faster (and still had my left hand) I took 4th place in the Challenge Roth (In Germany) in my second major triathlon.
    In 2007 I attempted the Norseman triathlon but suffered a severe sprained ankle and had to finish the alternate course.
