Pippa Middleton and her brother James, the siblings of Duchess of Cambridge Kate Middleton, have set off on a gruelling bike ride across the US.
Representing Britain, the pair are in team of eight that set off from San Diego, California on Saturday in a cross country race for charity.
The aim of the race is to ride 3,000 miles, passing through twelve states, in eight days to reach Annapolis, Maryland.
The sibling pair are joined by multiple team and solo riders in the 33rd annual Race Across America charity event.
Their aim is to raise money for the British Heart Foundation, which Pippa was recently announced as the charity's newest ambassador.
