Dutch researchers have told world record sprinter Usain Bolt to get a move on, and that the 100m sprint can be run in just 9.51 seconds.

Econometricians from Tilburg University say they have been able to work out the quickest speed it is humanly possible to complete the race.

A team analysed the records of 762 male athletes from between 1991 and 2008  before using something called extreme-value theory calculations to work out what could be done.

Their figure knocks a massive 0.18 seconds off Usain Bolt's current world record ... but then again he did pretty much stop for photos towards the line.
