She made it to the US research station at the geographic South Pole Tuesday after pulling two sledges for more than 700 km, up a glacier, over a mountain range and against stiff headwinds for nearly a month. She says it feels amazing to have reached the pole, where she plans a day's rest to replenish her supplies before hitting the ice again.

She's not sure if she'll make the record, but says that whatever happens next, she'll have the satisfaction of having made it solo from the coast to the pole.
