My new answer: Usain Bolt acheived a top speed of 27.28 mph or 43.90 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.
Who is the fastest man in the world? How fast can this person run? The current fastest man in the World (World record holder of the 100 m sprint race) is Jamaican sprinter Usain Bolt. Jamaican set a new men's 100m record of 9.58 seconds at the World Championships in Berlin, August, 2009. Bolt also holds the World record in 200m (19.30s) and 4 x 100m Relay (37.10s).
