Blue Peter presenter Helen Skelton is hoping to become the first person to use a bike to reach the South Pole. She is attempting to travel 500 miles (805km) across Antarctica and will cycle for large parts of it, as well as snowkiting and walking. She hopes to complete the trek for Sport Relief in 20 days.
At this time of year, the average temperature in Antarctica is -25C, but can drop to -50C. Severe coastal winds come from cold air flowing down off the interior ice sheet. Wind speeds can reach up to 125mph (201km/h) and average about 80mph.
