LONDON (AFP) ― Britain’s Prince Harry was due to arrive in South Africa on Monday as he makes his way to Antarctica for a gruelling trek to the South Pole.

The royal is taking part in a 335-kilometer race between three teams of four wounded military personnel, representing Britain, the United States and the Commonwealth (drawn from Australia and Canada).

The 29-year-old army attack helicopter pilot will trek alongside the British team in the charity race to the planet’s southernmost point, which is expected to take 16 days.

After arriving in Cape Town on a flight from London, the teams were to fly on Tuesday to the air base by Russia’s Novolazarevskaya Station, at the edge of the Antarctic continent.

Once acclimatized to the altitude and freezing temperatures, the teams hope to begin the race on Nov. 29. They aim to reach the South Pole around Dec. 17.

Each team has a mentor and a polar guide.

Harry is patron of organizers Walking With The Wounded, which raises funds to retrain injured troops and help them find new careers outside the military.

He launched the charity’s South Pole Allied Challenge in London’s Trafalgar Square on Thursday.

“All the men and women behind me have achieved so much just to get here, let alone actually walk to the South Pole,” he said, flanked by the competitors.

“It’s just a wonderful display of courage from their part.

“These guys aim to achieve something quite remarkable, and in doing so will prove to everybody else that even though you’ve lost a leg or lost an arm, or whatever your illness may be, that you can achieve pretty much anything if you put your mind to it.”

He added: “This trip is another way of reminding everybody that as Afghanistan draws down and these guys aren’t in the news any more... the support must continue.”

Trekking around 20 kilometers per day, the teams will be pulling 70-kilogram sleds.

They will likely endure temperatures as low as minus 35 degrees Celsius and wind speeds of around 80 kilometersper hour.

Speaking at London Heathrow Airport on Sunday before departing, British army veteran Ibrar Ali, whose right arm was amputated after a roadside bombing in Afghanistan in 2007, felt both nervous and excited about the challenge ahead.

“A bit like pre-tour when you’re just about sat at Brize Norton (airbase) when you’re just about to go out to Iraq or Afghanistan,” he said.

Speaking of Harry’s involvement, he added: ”He’s a great team member and just fits in really well so no different to anyone else.”

Harry, who is fourth in line to the throne of his grandmother Queen Elizabeth II, joined the Walking With The Wounded trek to the North Pole in 2011.

However, he had to come home early to be best man at his brother Prince William’s wedding.
