But there was no time to waste in a race to become the first person to
cross Antarctica alone from shore to shore without any aid or support.
So when O'Brady and Louis Rudd, a captain in the British Army,
unzipped their tents and saw the misery they would experience on the
23rd day of their journey, they confronted it like it was any other day.
They would consume warm fluids and high-calorie snacks, and push
through the unmatched exhaustion that comes from hauling a 300-
poud Norwegian sled, known as pulk, for 10 to 12 hours.
Each day these two competitors, who have been traveling miles apart
from each other and have not communicated each other, have
emerged amid an icy desert to battle the elements and one another.
They've felt pain and frustration, taken risks and shed tears.
As they skied through the whiteout on Monday, they stared at
compasses strapped to their chests to stay on course toward the South
Pole, unable to see up or down or side to side, with their sleds catching
on wavelike ridges of ice known as sastrugi; forcing the occasional
tumble. On this expedition, for both men, tripping and falling hard --
countless times -- is all part of the schedule.

File2:

O'Brady wakes up at 6:10 a.m. and lights his stove on the ice in the
vestibule of his tent. He boils water for this morning meal of oatmeal
with extra oil and protein powder.
While he finishes breakfast, he empties his and packs his pulk. By
then, it's about 7 a.m., which is when Rudd wakes up and lights his
stove, which he also rests in the vestibule of his tent.
Rudd's day starts with instant hot chocolate -- he's carrying more than
15 pounds of hot chocolate powder in his sled. He also eats a freeze-
dried meal of porridge or onions and eggs.
It's all about calorie loading on an expedition like this. Though both
men consume as many calories as possible , they still expend more
calories than they take in. After all, there are only so many calories
someone can carry in a sled and still be able to move it.

Both men also struggled to manage their perspiration. Sweat can be
deadly in a polar environment because moisture can freeze on the skin
when motion stops, which can send core temperatures plummeting
toward hypothermia. Both men independently addressed the problem
by skiing in just their base layers to stay cool and swear-free. Their
exertion kept them plenty warm despite the subfreezing temperatures.
They have been climbing more than 9000 feet from sea level to the
South Pole (altitude 9301 feet). They have felt the incline but haven't
always seen it, even on clear days, because there are rarely any points
of reference they can use to gauge slope or distance.
"You know by the pulk," Rudd said. "You're suddenly working 10 times
harder. You look around and you can't teel you're going uphill, but you
must be because you can really feel it."
