Pippa's pedaling for charity. Royal in-laws Pippa Middleton and her brother James are on a three-thousand-mile bike ride across America to raise money for the British Heart Foundation, for which Pippa is an ambassador.  


Representing Britain, the two are part of a team of eight that began the grueling trek Saturday in San Diego, California.  The 33rd Annual Race Across America will take the teams through 12 states in eight days with an eye to the finish line in Annapolis, Maryland.


Pippa and James are the younger siblings of the Duchess of Cambridge Kate Middleton, and sister-in-law and brother-in-law of the Duke of Cambridge Prince William.
