Pippa Middleton competed in a 56-mile cross-country ski marathon in Sweden today to raise money for charity, according to The Associated Press.

The sister of the Duchess of Cambridge, Kate Middleton, came in 412th place in the Vasaloppet ski race, finishing in 7 hours, 13:36 minutes, among 15,800 competitors.

Middleton's brother, James, who also competed in the race, finished in 6 hours, 47:27 minutes.

The siblings participated in the race to raise money for a children's charity.

"My brother and I are raising money for Magic Breakfast, a small registered charity that fights child hunger through breakfast clubs and delivering free breakfasts (bagels, cereal, juice and porridge) to thousands of state primary school children in the UK, particularly our inner cities," Pippa Middleton wrote on her fundraising page.

According to the website, she raised £7,602.00 ($12,037) from 119 donors.
