Pippa Middleton: 'Ski marathon was tiring' - video
The Duchess of Cambridge's sister completed the 56-mile fundraiser in Sweden at the weekend and gave a short video interview to journalists soon after.
Middleton, who finished 412th out of 15,800 skiers, told SVT that the race was "tiring" and described herself as an "average" skier.
In the short interview, she added that she had spent a couple of weekends preparing for the event.
Earlier this year, Barbara Walters denied bidding against Oprah Winfrey and Ellen DeGeneres for the rights to an exclusive interview with Middleton.
"ABC News does not pay for interviews," she said.
During the ongoing Leveson Inquiry into media ethics, it emerged that The Daily Mail is sent over 400 pictures of Middleton every day by picture agencies and freelance photographers.
