Is 20 mph Fast For a Human? Yes, If you run the entire hundred metres in 20mph, you will get a time of 11.1 seconds.
“The human body is a sturdy one, but only up to a point, able to withstand collisions of about 15 miles per hour, which is about as fast as an average person can run.”
40 MPH: The fastest speed humans can run. The current fastest human in the world is Usain Bolt, who can run at nearly 28 miles per hour —some streets have lower speed limits than that! Bolt holds the record for the 100-meter sprint, clocking in at 9.58 seconds, reports BBC.
Taking pesimistic point of view by considering my speed as the lowest limit (unless you are slower than me), average human (male) running speed is between 6 – 25 km / hr.
How fast is a 20 mph 40 yard dash? Obviously, it isn’t a 40 yard sprint from the blocks, but at 20 mph a player is covering 40 yards in 4.09 seconds.
We’ve seen humans experience, for a very brief period of time, as much as 40 Gs acceleration, which is 40 times the force of gravity—and they’ve survived.
The record for a marathon (26 and a bit miles) is 2 hours 1 minute 39 seconds. So about 13 mph. If you could keep up 17mph for 26 and a bit miles then you would be considered fast.
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.
17mph is about one mile in 3.6 min. As a 4 min mile is considered very fast, then, yes, you would generally be considered quite fast. IF you are running a mile. Usiah Bolt holds the record at 27.5 mph, but that speed was held only briefly during his world record 100 meter dash in 2009.
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.
— Steve in Davis, Calif. So far, the fastest anyone has run is about 27½ miles per hour, a speed reached (briefly) by sprinter Usain Bolt just after the midpoint of his world-record 100-meter dash in 2009. This speed limit probably is not imposed by the strength of our bones and tendons.
Humans need to have enough energy to continue running. The body requires glycogen (a glucose polymer) for energy, but burns it relatively quickly.
RULE 1: There’s a general rule that goes: maximum 10% incraese in mileage per week. You were increasing by 100% every day, without rest days for your muscles to recover. If you’re an absolute beginner, 6:15 minutes per kilometer is good!
There is no pace that is not respectable, just going out on races beats everybody in a couch. 5 min per Km on a 5K race, 25 min total, will get you just a bit above the middle on most flat 5K races. But for your age, it would not be particularly good, neither bad.
To achieve 4 Mins per KM and maintain it for 2–3 Kms will give you some serious gains if your running technique is not faulty. If you are not a professional athlete this your rate of speed is quite good. You can compare with the runners in other countries by running with an app like RaceRunner.
