Beijing: Athletics got the hero it has been craving for years when Usain Bolt lit up the Bird's Nest with his brilliance, his 100 metres victory ensconced as one of the images of the 2008 Olympic Games.

After years of one depressing doping scandal after another, the Games began with many leading figures warning that athletics was in real danger of alienating its fans forever and with it, losing its place as the heart and soul of the Olympics.

Bolt's stunning performances, and the excitement of the build-up to his races, ensured that, for sprinting at least, things are looking good.

Bolt's performance in breaking his own world record in 9.69 seconds, and the chest-thumping celebratory way he did it, thrilled the world.

Presence of greatness

When he put his head down to drive through the line and erase Michael Johnson's untouchable 12-year-old mark in the 200 metres with a run of 19.30 seconds, any doubters would have realised they were in the presence of greatness.

A third gold and a third crushing world record after an eye-defying third leg in the 4x100 metre relay completed his haul.

Bolt, who turned 22 the day after his 200 win and had 91,000 people singing him "Happy Birthday" as he stood on the podium, is a performer and character most sports would die for.

However, IOC president Jacques Rogge chided him for a lack of sportsmanship for tearing off on his victory lap instead of waiting to shake hands with his beaten opponents. Bolt said he just wanted to have fun.

In contrast, Lamine Diack, head of the International Association of Athletics Federations (IAAF), had nothing but praise for the jewel in his midst. Diack said Bolt had had more impact than any other athlete in Games history.

"He is great for our sport, he can help to build up our sport," Diack said.

Bolt's triple whammy was only part of a fantastic athletics programme for Jamaica, who took a clean sweep of the four sprint titles en route to six golds and 11 medals in all.

Their success, and Bolt's superhuman performances, invariably raised the question of doping, particularly as the 100 metres has been dogged horribly in that regard for so long.

Bolt, however, who won the world junior championships 200m at 15 and was the first junior to break 20 seconds, has hardly come out of the blue, and he dismissed the idea out of hand.

"I've been tested so many times in the competition I've lost count," he said. "We know we're good, we know we're clean. We work hard and any time you want to test us, it's okay."
