After braving biting winds and treacherous mountains to sled 250km across the Arctic Circle, Farah Idris mustered the strength for a headstand - before collapsing exhausted onto the snow.

The operations manager, of Hounslow, had endured four foot deep snow, temperatures of -40F and winds of up to 200mph on her six-day husky-drawn journey from Tromso, in northern Norway, to Jukkasjärvi, Sweden.

She completed the gruelling challenge on Friday, April 18, raising nearly £5,800 for wildlife charity the Born Free Foundation.

"In just one week, I was treated to so many epic moments and life-long memories from hiking to the top of a glacier, traversing on the slippery ice, sledding across fragile frozen lakes, navigating in between icebergs, jumping across deep crevasses, discovering mirages, sledding with uncontrollable huskies, watching reindeer run wild, golden eagles in all their glory and so much more," said the still-pumped adventurer.

"Regardless of my cuts, aches and bruises, my heart was pumping and I felt more alive than ever before. I was overcome by the outstanding magnificence around me - I was connected to our exquisite universe."

It was the latest in a series of sponsored challenges for Farah, who has previously conquered Mount Kilimanjaro and completed the London Marathon.

Although she was glad to get out of the cold, she said she was missing the 'adorable' team of five huskies who pulled her sled through the frozen wilderness.

The same could not necessarily be said for the team of 'very strict' ex-military instructors who led the trip, but she was grateful for their support and that of all her sponsors.
