With 100 days to go until the London Paralympic Games, South African sprint runner Oscar Pistorius says he is beginning to get nervous about competing.
The man known as "Blade Runner" said:
"One-hundred days out is a bit nerve-racking. It's just around the corner. The Paralympics is the pinnacle of what we train for - some of the happiest memories of my life were in Beijing".
He says, however, that he is fitter than ever and hopes to perform better than before.
