"This is basically my full-time job at the moment, making sure that we pull this off," he told BBC Radio 2 earlier today.

Championed by Prince Harry, the Games will see sick, injured and wounded service personnel compete in eight sports at the Queen Elizabeth Olympic Park.

More than 300 competitors from 13 countries are expected to come to the British capital for the event, which will be held from September 10 to 14.

"It's been a real struggle actually," said Prince Harry.

"Anyone listening out there, I would say if you're going to try and plan something this big in under a year, make sure you've either got [Organising Committee chairman] Sir Keith Mills with you or don't bother doing it at all.

"It's been great."

The Games are in the mould of the Warrior Games in the United States.

Prince Harry added: "We decided it [the Warrior Games] was such a wonderful concept, we should steal it, make it bigger, make it better and bring it back home.

"We're still trying to work out whether we do it next year or the year after and whether it's going to be within the UK or whether it's going to be abroad.

"But the legacy has already started and if we can use it as a stepping stone for some of these individuals to move on to the Paralympics, great.

"If some of them want to use it as a one-off to get themselves back on the road and then as a stepping stone to employment, then just as good.

"We will use the Invictus Games for as long as it's needed."

Competition will take place in athletics, archery, wheelchair basketball, road cycling, indoor rowing, wheelchair rugby, swimming and sitting volleyball.

A crowd of up to 5,000 people are expected for the Opening Ceremony on September 10, with the Royal Air Force to perform a fly-past during the Ceremony, which will be on the South Lawn of the Queen Elizabeth Olympic Park.

There will also be a series of ceremonial displays and a performance of the official Invictus Games anthem, penned by Chris Martin from Coldplay.

Tickets for the Ceremony as well as for all sessions for the Games, cost £12.85 ($22/€16) and can be purchased here.

And tickets for the Closing Concert, with performances from the likes of Foo Fighters, Kaiser Chiefs and James Blunt, will go on sale at 9am British Summer Time tomorrow and will be available from the same website.
