Prince Harry has paid tribute to the courage of the injured servicemen he is due to lead in a race to the south pole to raise money for charity.
The Prince will join a team of four injured British soldiers as they take on groups from the Commonwealth and the United States in the 200-mile Walking With the Wounded charity trek.
In the speech in Trafalgar Square, Harry said the feat would set an example to all that "you can achieve pretty much anything if you put your mind to it."
