What is the top speed a human can run?

The fastest speed ever officially recorded for a human being is 46.04 kilometres per hour (28.61 miles per hour), set by Usain Bolt of Jamaica in the 100-meter sprint final at the 2009 World Championships in Athletics in Berlin, Germany. However, it is worth noting that this record is for a specific event under controlled conditions on a synthetic track. In general, the average top speed that a human can run is much lower, with most people able to reach speeds of around 24 to 29 kilometres per hour (15 to 18 miles per hour) in short sprints.
