Pippa Middleton completed a 56-mile cross-ski marathon in Sweden on Sunday.

The sister of Duchess of Cambridge- the former Kate Middleton- finished 412th in the women's category, completing the race in 7 hours 13 minutes. There were 15,800 total competitors. She told local stations that the race was tiring, and that she spent "a couple of weekends" preparing.

Pippa and her brother James participated in the Vasaloppet ski race to raise money for the children's charity Magic Breakfast. The race is one of the oldest in the world. The winner finished in 3 hours 38 minutes.
