World's Fastest Man* The Incredible Life of Ben Johnson by Mary Ormbsy Sprinter Ben Johnson always had a unique relationship with time. At his peak, he could bang out practise runs that consistently finished exactly when his coaches dictated, down to one or two tenths of a second. His feel for the stopwatch was uncanny. How Johnson measures longer intervals is less well known. 36 years have slipped by since he ran 9.79 seconds in the 100-metre final at the 1988 Seoul Olympics.
