South Pole bike ride for TV presenter

Daredevil Blue Peter presenter Helen Skelton is attempting to become the first person to use a bike to reach the South Pole. The 28-year-old will begin her gruelling 500-mile ski, kite and ice bike journey across Antarctica for Sport Relief on January 1 next year.

Skelton, whose previous exploits include high-wire walking between the chimneys of Battersea Power Station and becoming the first person to solo kayak the length of the Amazon, is aiming to set a new world record for the longest bicycle journey on snow.
