Pippa Middleton relaxed between ski runs on Sunday in Switzerland. She was off at a mountain resort with friends prepping for the Vasaloppet 2012 cross-country skiing event. The 56-mile competition will be held in Sweden on March 4, with both Pippa and her brother James participating for charity. The event benefits the Magic Breakfast, a children's hunger charity. The snowy getaway came as a break for Pippa from her London work routine, and possibly, a new romance. After breaking up with boyfriend Alex Loudon late last year, Pippa's rumored to be dating George Percy, a longtime friend and heir to the title of Duke of Northumberland.
