The fastest human, Usain Bolt, recorded a top speed of approximately 27.8 miles per hour (44.72 kilometers per hour) during the 100 meters race at the 2009 World Championships in Berlin.
This incredible speed was achieved over a short distance, reaching his peak just a few strides into the race. Factors like biomechanics, training, and genetics contribute to such remarkable speed capabilities, making Bolt a phenomenal athlete. The average human, by contrast, runs at a much slower speed, highlighting just how extraordinary this achievement is.
