Chambers hungry as ever
Dwain Chambers admits the clock is ticking on his career, but he is in no mood to stop.
The former drug cheat will line up in the heats of the 100 metres at the World Championships in Moscow on Saturday still determined to make an impact on the global stage.
That the 35-year-old's one and only world 100m medal dates back to the last millennium - he won bronze in Seville in 1999 - is testament not only to his past misdeeds but also to his longevity.
"That medal is actually on my medal shelf and it's a medal that I want to capitalise upon, because on the world stage I haven't won any major medals in the 100m since back in that period," said Chambers, who tested positive for steroid THG in 2003.
"On a personal note I want to do my best and get into the final, and once I'm in the final that's where experience will play its role for me.
"If I'm good enough on the day to perform then I'll be really happy.
"I don't have much time left in the sport so I want to achieve as many things as I can."
This could be Chambers best, and perhaps last, chance to make a global final given the depleted field, with defending champion Yohan Blake missing through injury and Tyson Gay, who has run the fastest time in the world this year, because of his own failed drug test.
He added: "This is the first time in 10 years I've been able to run distraction-free. I just want to see how far I can go and how much fun I can have while I can."
One man who could earn a PhD in having fun is world record holder Usain Bolt.
He was laughing and joking with his Jamaican team-mates at today's open training session, strolling up and down the track and then receiving a massage.
His most strenuous work out appeared to come when he skipped off, in the opposite direction to the waiting journalists.
His training partner, the Olympic 200m bronze medallist Warren Weir, spoke for him, saying: "He's in pretty good shape."
Bolt's best time this year is 9.85 seconds, set at the Anniversary Games despite a start he himself described as "horrifying".
It is rather sluggish by his own stratospheric standards, but Michael Clarke, the head coach of the Jamaican team, reckons there is more to come.
"As for his peaking he's still a young man and there's still a lot more in him to come," he said.
"It would be good if he can have another world record, but let's see what happens.
"I believe that he will do as well as he did in the past."
