MOST New Year's resolutions have something to do with losing weight, doing more exercise and possibly taking up a new hobby.
But Sydney-based adventurers James Castrission and Justin Jones just want to sit still and eat up after reaching the South Pole yesterday morning - the halfway point in their attempt to become the first duo to trek unassisted to and from the bottom of the world.
''It was such an exhilarating feeling to know we were skiing towards what has been a childhood dream for so long,'' Castrission, 29, said.
After 62 days, 1150 kilometres and average temperatures of minus 25 degrees, the pair reached the South Pole on their skis shortly after 7.30am.
To celebrate they ''ran around the Earth a few times''.
But the party atmosphere was short lived as the pair contemplated the 1150 kilometres that lie between them and Hercules Inlet, which they must reach in the next 28 days to achieve their goal.
''There's a feeling of, 'Gee we have a long way to go', the feeling of isolation and knowing we are so far away from our starting point,'' Castrission said in a podcast recorded just after the pair reached the South Pole.
Castrission and Jones, 28, have lost about 30 kilograms between them and are eating only half their daily rations of nuts and energy replacement powders.
Injury has forced them to rest for four of the 62 days they have travelled.
''We have 28 days to get back. That's a marathon a day,'' Castrission said.
He hopes a tailwind will make for an easier return journey. If they do not make it in time, they will miss the last flight of the season out of Antarctica. They are already 10 days behind schedule due to a series of blizzards.
''It's a real race against the clock. We don't know if we are going to make it, but we are going to give it everything we've got,'' Castrission said.
The pair, who are raising funds for youth cancer campaign You Can, have been dragging everything they need to survive the three-month trip in two 160-kilogram sleds.
In 100 years of polar adventures, no one has trekked to and from the South Pole without a support team.
In 2008, Castrission and Jones, were the first people to kayak from Australia to New Zealand.
