13:23 – The band and choir lead the crowd in a rendition of God Save the Queen as a beautifully-observed Drumhead Service comes to a close.
Lee Valley is now being prepared for the finals of the Invictus Games athletics which commence at 2pm.
Invictus is Latin for unconquered, a word that embodies the fighting spirit of these men and women and what they can achieve post-injury.
We've already seen that spirit in abundance during the heats and are we are sure to see some inspirational moments in the upcoming finals session.
13:10 – The Band of Her Majesty's Royal Marines HMS COLLINGWOOD are joined by the choir of the Royal Hospital School, Holbrook to get the Drumhead Service under way.
Prince William and Harry are both present to pay their respects as Chaplain of the Fleet, The Reverend Scott J Brown CBE QHC, pays homage to those fallen in World War I and all affected by the events of September 11 2001.
12:50 – The heats have now drawn to a close and the crowds are gathering for the Drumhead Service at 1pm.
This tradition, which goes back many centuries, is a church service conducted in the field with drums draped in the appropriate colours to create a makeshift altar and is continued to this day.
Great to see so many present to celebrate the 'Invictus spirit' through sporting achievement.
12:00 – Prince Harry arrived early to take in the opening heats of this morning's athletics as the inaugural Invictus Games, presented by Jaguar Land Rover, got under way at the Lee Valley Athletics Centre.
The international sporting event for wounded, injured and sick service personnel is championed by the Prince and kicked off with a spectacular opening ceremony last night at London's Queen Elizabeth Olympic Park.
Tuesday saw the first medals of the competition presented by Prince Harry as teams from 11 nations competed in a special driving challenge in both a Land Rover Discovery and a Jaguar F-TYPE.
And it was Australia's Sarah Archibald and Matthew Taxis who clinched the first gold medals at Jaguar Land Rover's Design and Engineering Centre in Gaydon.
The athletics is the first of nine different sports taking place across four days and got off to a great start with fans on hand to cheer on those taking part in the early-morning action.
