Blue Peter presenter Helen Skelton has completed her gruelling 500 mile expedition across Antarctica for Sport Relief.
The 28-year-old endured numerous blisters, a hacking cough, stomach troubles and a bad bout of dehydration during her 18-day adventure.
She travelled by ski and kite, and became the first person to use a bike as part of an expedition to the Pole.
