The Blue Peter presenter Helen Skelton, 28, covered 100-kilometres by kite ski along with her Norwegian co-adventurer Niklas Norman, in 7 hours and 55 minutes, benefiting from favourable winds - setting the world record for the Fastest 100-kilometres by kite ski.
The Guinness world record for the longest line of skiers consisted of 232 skiers and was achieved by Iwate Ski Place Association, Iwate Winter Resort Kyougikai and Touhoku Resort Service Co. Ltd. (all Japan) at Hachimantai Resort, Iwate, Japan.
Guinness World Records also recognized the world record for the largest ski lesson, attended by 594 skiers who were instructed by Hansjürg Gredig (Switzerland) of the Swiss-Snowsport School at Sarn-Heinzenberg (Graubünden), Switzerland.
"The Blue Peter presenter Helen Skelton has set a new world record for the fastest 100-kilometre kite-ski, as she battles to reach the South Pole," reports the Telegraph.
"She covered the distance, along with her Norwegian co-adventurer Niklas Norman, in 7 hours and 55 minutes, benefiting from favourable winds."
The rules are so tough that Helen has only been allowed to take a toothbrush head without the handle, although she has managed to keep up appearances in one department.
'My one concession is that I had my eyeliner tattooed on so I could dispense with bringing make-up,' she admitted.
The trek is the latest challenge she has undertaken in the name of charity and all her sponsorship money will be donated to Sports Relief.
Helen previously became the first person to solo kayak the length of the Amazon for Sports Relief in 2010 and undertook a high-wire walk across Battersea Power Station for Red Nose Day in 2011.
Officials at Guinness World Records issued the following statement:
"We are aware of explorers who have achieved longer distances, but Helen Skelton's application was the first that Guinness World Records had received specifically for the 100-kilometre distance.
"Based on the GPS data received by satellite from the Antarctic, Guinness World Records has confirmed that Helen Skelton achieved a world record by covering 100 kilometres in seven hours 28 minutes."
