On Saturday, South African sprinter Oscar "Blade Runner" Pistorius will become the first double amputee to compete in track & field at the Olympics as he lines up in the heats for the men's 400 meters. Pistorius has already established a storied career in the Paralympics, but has long wanted to compete against able-bodied athletes in the Olympics as well. After an extensive battle over the question of whether his prosthetic legs gave him an unfair advantage, Pistorius won his chance at the starting blocks. He is also running the 4x400m relay.
Pistorius is not expected to medal or even to advance to the finals of his event, but his performance will be historic, regardless. He continues to stir debate--as well as to inspire millions worldwide with his efforts.
