Double amputee Pistorius, who has been dubbed Blade Runner, was out of the Olympic race earlier today after his team mate crashed out of the second heat relay.
However after an appeal the South African team has been reinstated and granted a place in the 4x400m final.
Pistorius said on Twitter: “Thank you Lord. Emotional rollercoaster.”
Here’s what happened to Pistorius and the South African team earlier today.
