(CNN) -- Double amputee sprinter Oscar Pistorius has moved a step closer to realizing his dream of participating in the Olympics after running the 'B' standard qualifying time for next year's Games in London. 

The 24-year-old, who was born without fibulae in both legs, clocked 45.61 seconds to win the 400m race at the Provincial Championships in his home town of Pretoria in South Africa on Wednesday. 

Dubbed the 'Blade Runner' because of his carbon fiber prosthetic limbs, Pistorius must now run 0.6 seconds faster to be granted automatic qualification. But his time could still be good enough to earn him a place in the South African team depending on the performance of other athletes. 

After narrowly missing out on the time required for the Beijing Olympics, the Johannesburg-born athlete expressed his delight at the achievement on his Twitter page. 

"One of the best nights of my life. Ran a 45.61sec 400m Olympic qualifying time and fastest time in South Africa," Pistorius, whose legs were amputated when he was just 11 months old, wrote. 

"Thanks to everyone who has supported and believed in me in my Quest to 2012 London Olympics. One step closer. I'm hungry for it." 

After finishing sixth at his National Championships in 2007, Pistorius was blocked from competing alongside his able-bodied counterparts as his blades were considered to give him an unfair advantage. 

But in 2008 the Court of Arbitration for Sport ruled in favor of the four-time Paralympic champion after a lengthy legal battle with the IAAF.  QUESTIONS:
