Irony was at its cruellest as Usain Leo Bolt pulled up hurt in his final competitive race to end, in a cry of pain and agony, a decade of dominance that is unrivalled in the history of track and field.
Bolt failed to finish the men’s 4x100m relay race of the World Athletics Championships here after he pulled a hamstring at the home straight.
The astonishing turn of events marred what was expected to be a golden farewell.
Running the final race of his career, the 30-year-old Bolt, after taking the baton from his Jamaican teammate Yohan Blake, suffered cramps on his left hamstring as he tried, in vain, to chase down the British and American rivals in the last lap of the race.
Needing to make a lot of ground, Bolt began his familiar initial long strides but could not produce the trademark explosive burst of speed and suddenly stumbled, hobbled a few strides before falling on the track in pain and agony.
