Donovan Bailey, the current world record holder, completed a 100 metre sprint in 9.84 seconds (average 36.6 km/hr). Provided that the smoke did not fill their lungs or sting their eyes so badly to temporarily blind them, someone running at this speed would be able to outrun the fastest fire over a distance of 100 metres.
However, lacking the benefit of years of training for 10 explosive seconds on the track, and weighed done by our bushfire attire (heavy boots and overalls), many of us would be lucky to run at half the speed of Bailey, let alone as fast as the Boonoke fire!
