Pistorius, who has double below-knee amputations since he was 11 months old, competes in T44 (single below-knee amputees) events though he is actually classified in T43 (double below knee amputee). Sometimes referred to as the "Blade Runner" and "the fastest man on no legs", Pistorius took part in the 2004 Summer Paralympics in Athens and came third overall in the T44 (one leg amputated below the knee) 100-metre event.
Despite falling in the preliminary round for the 200 metres, he qualified for the final. He went on to win the final in a world record time of 21.97 seconds, besting a pair of American runners both possessing a single amputation, Marlon Shirley and Brian Frasure.
