Lewis Clarke was 16 years old when he skied to the South Pole. The year 11 student from Bristol spent 48 days skiing 702 miles along the Hercules Inlet route.
On the expedition, he only had one day off. Skiing 8 to 9 hours a day, he covered about 18 miles a day, battling against gale force winds and temperatures as low as -40.
After his 7 week expedition, he literally went straight into his GCSE mocks and then into the real exams. (in August he got his results – 7 A*s and 3 As) He actually took his revision with him to Antarctica!
And this wasn't even the first time he had broken a world record (and still holds the record). When he was 12, Lewis and a team of friends became the youngest team to ever swim the Channel in relay.
