- Bolt will retire after IAAF World Championships
- Jamaican is most successful sprinter in history
- Will aim to add to his 11 world titles
The age of Usain Bolt is nearly over and so the present must be cherished.
Bolt, the fastest man in history, one of the greatest sportsmen to have ever lived, will run his last race at the World Athletics Championships in London.
He will retire having left his mark on history: the first man to win three 100m Olympic titles, the world record holder in both the 100m and 200m, a winner of 23 major gold medals.
His legacy is assured. No man has run with such speed or enjoyed such longevity. The 30-year-old's extraordinary achievements will be looked back upon with wonder by future generations.
They will watch replays of the young Bolt of Beijing, hushing the crowd on the starting blocks before bang... history -- his arms raised, thumping his chest, clocking a barely believable 9.69 seconds to shatter the 100m world record.
The 21-year-old's speed was jaw-dropping, the other eight men in a distinguished field left trailing in his wake.
They were in a different race and this 6ft 5in newcomer was from another planet.
Two more gold medals followed on the Chinese capital's lightning-quick track, his 2008 coronation as sprint king complete.
Hearts and imaginations were captured and he has been loved ever since.
