Prince Harry has been getting used to life in the sub-zero conditions of the Antarctic ahead of his charity trek with wounded servicemen and women.
The 29-year-old made some final adjustments to the kit he will be taking with him on the 200-mile expedition and took part in some skiing training to acclimatise.
Harry and the teams removed any non-essential items from the sleds they will haul to make them as light as possible.
Each person's kit has now been weighed ahead of their flight to the second base camp at 87 degrees south, which they hope to take on tomorrow, weather permitting.
The Walking With The Wounded South Pole Allied Challenge 2013, of which Harry is patron, will see the participants race across three degrees to the South Pole.
All 12 injured service personnel from Britain, America, Canada and Australia have overcome life-changing injuries and undertaken challenging training programmes to prepare themselves for the conditions they will face in Antarctica.
Trekking around 15km to 20km per day, the teams will endure temperatures as low as minus 45C and 50mph winds as they pull their 70kg sleds, known as pulks, towards the southern-most point on the globe.
They hope to reach the geographic South Pole by December 16.
The UK Team Glenfiddich have been joined by Harry, Team Soldier On from the Commonwealth counts actor Dominic West among their number, while the US Team Noom Coach lines up alongside actor Alexander Skarsgard.
Each team also has a mentor and a polar guide.
Each team will represent and raise funds for military charities from the constituent nations: Soldier On from Canada, Soldier On from Australia, Soldiers to Summits from the US and Walking With The Wounded from the UK.
