Lieutenant Scott Sears is attempting to become the youngest person in history to walk solo to the South Pole, completely unassisted and unsupported.
The 26-year-old will travel to Hercules Inlet at the southern end of Antarctica's Weddell Sea on the 7th November, and then will walk and ski solo over crevasse fields, glaciers and the Antarctic plateau for up to 45 days.
Weather will vary between 0 and -60 degrees centigrade with 100mph winds expected.
Mr Sears, who is 6ft 5 inches tall, will pull a pulk weighing around 100kg containing all his food, fuel and equipment and burn approximately 10,000 calories per day.
He will cover the 1,130 kilometres to the South Pole without help or resupply of any kind, arriving around Christmas Day.
Mr Sears aims to raise £25,000 for the Gurkha Welfare Trust to help rebuild communities shattered in the 2015 Nepalese earthquake.
This will include a school in the hometown of a Rifleman Suraj, a fellow soldier who was killed while serving with him in Afghanistan.
The Gurkha Welfare Trust provides financial, medical and development aid to Gurkha veterans, their families and communities.
Last month, a British Army’s team also left for Antarctica aiming to become the first all-female team to ski from coast-to-coast across the continent.
