More than 400 athletes from 13 competing nations have come to London for the inaugural Invictus Games. The brainchild of Prince Harry, the event will see athletes compete in nine sports across four days. It promises four days of intense competition but also amazing stories of athletes who have used sport to lead their rehabilitation from the injuries and illnesses they suffered serving their countries.

Before the action moves to the Olympic Park, it gets under way with athletics from the Lee Valley Stadium. The British Armed Forces team captain, Dave Henson, will hope to get the team off to the best start in the men's 200 metres, and GB Paralympian Derek Derenalagi will not only take part in the throwing events he contested at London 2012 but will also get his blades going in the sprint events.

Jonathan Edwards introduces the coverage with commentary by Steve Cram, Mike Costello and Baroness Tanni Grey-Thompson. Show less
