David Weir won silver and bronze in Athens in 2004 and has since become Britain's top wheelchair racer.
The 29-year-old from Surrey excels on the road and track. He won his third London Marathon in a row this year and grabbed three golds and a silver at the 2006 Paralympic World Championships in Assen.
He also has experience of the Bird's Nest Stadium after winning a 5000m race in a test event earlier this year.
Weir has superb chances in the 400m, 800m, 1500m, 5,000m and marathon, but will have to deal with Aussie Kurt Fearnley.
