Pippa Middleton's athletic prowess was once again on display this weekend, as the 28-year-old joined thousands of other competitors in a grueling, 56-mile cross-country skiing race in Switzerland. 


The famous sister of Kate Middleton, the Duchess of Cambridge, took to the snowy hills with her brother James to help raise cash for the Magic Breakfast charity, which provides pre-school meals to poor inner-city children in the U.K. 


Pippa finished the race in 412th place (seven hours, 13 minutes and 36 seconds), an impressive number considering the more than 15,000 other skiers that took part. 


Per Strid, a spokesman for the Vasaloppet race, one of the oldest events of its kind in the world, told The Daily Mail: "I must congratulate Pippa – she had a fantastic performance. What she achieved was really impressive for a first timer. She was obviously very fit and in very good shape."


Speaking at the finish line in Mora, Pippa said: "It was incredible and it was faster than I thought I would manage. Now I'm going to rest and put my feet up."


Don't expect one of the world's most eligible bachelorettes to sit idle for long. Pippa has already said she will work to boost the profile of the Dame Kelly Holmes Legacy Trust, which mentors young people who are disadvantaged, in the months leading up to this year's London Olympics.


"Pippa is going to be doing something for my own charity leading up to the Games," Dame Kelly told the UK Daily Telegraph. "I'm not really supposed to talk about it yet, so I can't tell you anymore."


Something sporty, perhaps? Stay tuned.
