Middleton siblings are often accused of cashing in and milking their new royal connections after their sister Kate married Prince William and have been in spotlight since then.

However, this time Pippa and James have done a real good job, they have raised about £12,000 for charity.

While the Duchess of Cambridge, Kate Middleton, is seen making frequent public appearances at military and charity events alone these days, her siblings Pippa and James are busy raising charity to aid poverty-stricken children and other causes.

Recently, the 28-year-old and her brother participated in Vasaloppet cross country ski marathon to raise money for the Magic Breakfast charity that provides free breakfast to poor British school children, Daily Mail reported.

Pippa finished 56 miles (90 km) cross-country skiing race from Salen to Mora in just over 7 hours (seven hours 13 minutes 36 seconds, to be précised) locking 412th spot out of total 1734 women racers while James finished nearly 26 minutes ahead of her sister.

We made it! James and I just wanted to say a huge thank you for your incredible support for our cross-country ski challenge in Sweden, Daily Mail quoted her as saying.

We are truly grateful and appreciate the kindness and generosity you have all shown, she said. It was one of the best sporting adventures we have both participated in and we couldn't have enjoyed it more.

The naturally tall and skinny, Pippa said, It was porridge that morning at 6 am that helped her make it to the finish line.

Thank you so much again and please let us know if any of you are doing any charity challenges in the future - we would love to support you, she said.
