Lauded Paralympian Oscar Pistorius ran the 400 meters in London on Saturday -- finishing second in his heat in 45.44 seconds, advancing to Sunday’s semifinals. In the process, the South African runner became the first-ever double amputee to run in the Olympic games. Pistorius will also compete as part of South Africa's 4x400 relay team, but he isn't expecting to take home a medal at this year's Olympic Games.

"I'm not expecting to win!" the single stud, lovingly nicknamed Blade Runner, tells Us Weekly, slamming reports that argue his lighter-than-normal carbon-fiber blade prosthetics give him an advantage. "Scientific tests prove I have no advantage. That's all in the past," he continues.

Racing for the first time August 4, Pistorius already has plans to kick back and indulge in some R&R after the London Games. "I look forward to some time of. I have racehorse, love my dogs and enjoy fishing," he explains. "I'd love to take up architecture and I'm a keen painter," says former Italian Dancing With the Stars standout Pistorious.
