Oscar Pistorius of South Africa is today's Olympian on my blog.
His legs were amputated when he was 11 months old but he didn't let that stop him from becoming a world class athete.
He holds the world record in the 100m for T44 amputees (10.91 seconds) and he just won the Gold medal in the 2008 Beijing Paralympics.
To put his world record in perspective, it is exactly one second slower than the bronze medal winner in the men's 100m race in the 2008 Olympics; and Oscar would have won the silver medal if he raced in the Women's 100m race in the 2008 Olympics.
Oscar almost qualified for South Africa's 2008 Olympics 400m team (he missed it by 0.7 seconds).
You can see Oscar run at the end of Nike's "Courage" commercial
