What's The Human Speed Limit?
Matthew Herper, 05.14.04, 3:00 PM ET
How fast can a human being run? Right now, the theoretical limit is just under 30 miles per hour--but a new era of gene therapy could soon extend our species' capacity for speed.
Current runners already are touching the limits of what can be accomplished with the bodies nature gave them. "We're very close to the edge," says Peter Weyand, an assistant professor at Rice University. He says record-setting sprinters such as Michael Johnson and Donovan Bailey hit top speeds of as much as 27 miles per hour--but only briefly. "A dog, an ostrich, a cheetah, they can blow us away," says Weyand. "And the materials they use to run--their bones, their muscles, their tendons--are no different than ours."

As of June 2000, the fastest running human is Michael Johnson, the American track and field star who on August 1, 1996 set the world record of running 200 meters in 19.32 seconds. Johnson, by doing this, won an Olympic title in Atlanta, Georgia and broke the longest standing field record of the time; Pietro Mennea's 1979 record of 19.72 seconds. Johnson's record can be calculated to equal 10.35 m/s or 37.267 km/h. Johnson's events also include the 400 meter run which he ran in 43.18 seconds ranking him number one in the world in 1999. This broke the 11-year old record of American Butch Reynolds (43.29s). In this category, Johnson was undefeated throughout his career with forty four consecutive victories. An interesting fact to know is that in the animal kingdom Michael Johnson would be considered relatively slow; the cheetah, one of the world's fastest land animals, can sustain a top speed of about 30 m/s or 100 km/h -- three times the speed Michael Johnson can achieve

Maybe 30 MPH tops, and that's an athlete running at peak performance. A crocodile can run faster than that in short bursts... so don't stand too close. ;)
