(CNN) -- He's "the fastest man on no legs," or -- as his sponsor's high-profile advertising campaign put it -- "the bullet in the chamber."

He is Oscar Pistorius, the "Blade Runner" who is changing the world's perception of what is acceptable on an athletics track.

Born without a fibula bone in each leg, the South African is the first double amputee to run at the world championships, and next year he will be the first to race at the Olympics.

"I think next year's going to be quite a big year, as far as demand on my performances," the 24-year-old told CNN.
