Has a human ever run 30 mph?

Answer 1

My new answer:

Usain Bolt acheived a top speed of 27.28 mph or43.90 kph in travellng the 2 fastest consecutive 60-70 & 70-80, 10m splits ever of .82 seconds.

We'll leave out 4x100m splits as I don't have them for Team Jamaica's WR from Beijing.

Old answer:

Since Usain Bolt became the 100m WR holder with a 9.68, I don't know if this figure still stands but in the 1996 Atlanta Olympics, Donovan Bailey in a WR time of 9.84 secs, covered a 10m portion at 12.1 meters per second. That would translate to about 27 MPH or about 43 Km/h. Both he and Maurice Greene hit a 10m section of the 100m final of the 1997 World Championships at 11.91 m/s... Greene ran a 9.86 and Bailey ran a 9.91. That would mean both reached a speed of roughly 26.5 MPH. Considering that, even the reductions the WR has taken in the last 12 years, it would be okay to assume 27-28 MPH is the fastest speed ever attained by a person running. Though Bob Hayes, in 1964, ran his leg of the 4x100m relay in 8.50 seconds.

Answer 2

Usain Bolt is the fastest human, ever, winning many Olympic gold medals. His fastest speed was a little bit over 27 mph. So your answer is 'no'.

Of course, we know nothing of fast humans before they started timing sprints and recording the times.

Answer 3

The fastest speed that a human being has ran is 27.28 mph or 43.90 kph. This was run by Usain Bolt in the fastest consecutive races. Speed is down to the muscle tone and fitness as examples.

Answer 4

No, it is physically impossible for a human to run at 30 mph. The fastest recorded human running speed is around 27.8 mph, achieved by Usain Bolt.

Answer 5

Slower than a cheetah.

Answer 6

No

Answer 7

20 mph
