Skelton halfway in Pole challenge
Helen Skelton has reached the halfway point in her South Pole challenge and looks to have added another world record to her haul.
The Blue Peter daredevil attempted to set a record for the fastest 100km kite surf, covering the distance across Antarctica in seven hours and 55 minutes.
Helen, 28, has completed the equivalent of heading from London to Northampton in temperatures which plunged to -48C.
Evidence of the attempt has been beamed to Guinness World Record officials in order to verify her claim to the title.
The kite surfing stunt is part of a 500-mile dash to the South Pole for Sport Relief.
She has now passed the 250-mile mark in seven days, during a journey which also sees her skiing without a kite and pedalling a bike, which is said to be a world first.
The presenter has previously set two records for her solo kayak along the Amazon for Sport Relief in 2010.
So far on this journey she has battled on through tummy troubles, snow storms, blisters and dehydration.
She said: "250 miles down, 250 miles to go. I know I've got a lot of hard work still to do but at least I am closer to the end than the beginning now. Every single day here is tough so all I can do is take each one at a time and get through it."
Her preparations and the challenge itself will feature in a nine-part series for BBC1 and CBBC, expected to begin later this month. Donations for the charity challenge can be made at sportrelief.com/helen.
