Pistorius was invited by the IAAF to take part in what would have been his first international able-bodied event, the 400-metre race at the IAAF Grand Prix in Helsinki, Finland, in July 2005. He was unable to attend, however, because of school commitments.
On 13 July 2007, Pistorius ran in the 400-metre race at Rome's Golden Gala and finished second in run B with a time of 46.90 seconds, behind Stefano Braciola who ran 46.72 seconds. This was a warm-up for his appearance at the 400 metres at the Norwich Union British Grand Prix at the Don Valley Stadium in Sheffield on 15 July 2007.
