Pippa Middleton donned lycra on Sunday for a 54-mile charity bike ride from London to Brighton.
The Duchess of Cambridge's younger sister and brother James joined 22,000 riders to take part in the event in their roles as ambassadors for the British Heart Foundation (BHF).
Miss Middleton said: "This event is testament to the fact that cycling is such an inclusive sport that everyone can enjoy.
"Through the money raised, the BHF can continue to help the millions of people affected by coronary heart disease - the UK's single biggest killer."

Billed as "Europe's largest and oldest charity bike ride", the annual race was launched 40 years ago.
In that time it has raised more than £65 million for heart disease research. Just 36 took part in 1975; today more than 20,000 saddled up for the ride.
