Teenager Parker Liautaud, who grew up in London, has announced today he is going to attempt to break the land speed record for crossing Antarctica - at just 19 years old.
He wants to cross from the Antarctic coast to the South Pole in 22 days, meaning he'll have to notch up over 18 miles a day in temperatures as low as -35°c.
He'll also be gathering snow samples along the way to help with research into climate change.
