Bunbury athlete Brad Scott hopes to capture the Paralympic gold medal that narrowly eluded him at both the Beijing 2008 and London 2012 events.
Scott, 28, who was born with cerebral palsy, won a silver medal in the T37 800 metres in Beijing, just two years after he started running.
He then won bronze in the same event in London 2012 and won a silver medal in the T37 1500 metres.
The T37 800 metres will not be held at the Rio event, meaning Scott has spent the last two years preparing solely for the 1500 metre event.
Scott’s main rival will again by Irishman Michael McKillop.
McKillop won gold in the T37 800 and 1500 metre events ahead of Scott in London and currently holds the T37 1500 metre world record.

McKillop and Scott also finished first and second in the T37 1500 metre event at the 2015 IPC Athletics World Championships in Doha.
The Rio 2016 Paralympics run until September 18.
