At high school, he was so good that his personal fitness coach said she was unaware for six months that he ran on prosthetic legs.
But he was initially banned from competing in the Olympics in Beijing by the International Association of Athletics Federations (IAAF) on the grounds that his blades gave him an unfair advantage.
That decision was later overturned on appeal at the Court of Arbitration for Sport (CAS), although he ultimately failed to meet the Olympic qualifying standard time.
Off the track, Pistorius is an adrenalin junkie, with a love of speed reflected in a passion for motorbikes.
Four years ago he crashed his boat in a river south of Johannesburg, breaking two ribs, an eye socket and his jaw.
He also once owned two white tigers but sold them to a zoo in Canada when they became too big. (AFP) AT AH
