Pippa Middleton is coaxing people to join the London to Brighton bike ride to be held on June 19. The younger sister of the Duchess of Cambridge, Kate Middleton is promoting the cause in her capacity as the brand ambassador of the British Heart Foundation. Pippa is persuading people to join the 54 mile challenge to raise money for charity.

The 32-year-old had participated in the challenging bike ride last year, which was the 40th anniversary of the event, along with her younger brother James. The brother-sister duo regularly participate in sports events.

“It was an unforgettable experience. There was such a great atmosphere throughout the day,” Pippa said, urging people to sign up for the London Brighton bike ride. She added that t he view from Ditchling Beacon, the highest point of the ride was unbeatable.

Pippa, who is now back with her ex-boyfriend James Matthews, said that through the London Brighton bike ride people could enjoy the inclusive sport. She added that they could also help raise money for charity. Pippa said cyclists could help BHF in its endeavor to “help the millions of people affected by coronary heart disease – the U.K.’s single biggest killer.”

The BHF's London to Brighton bike ride is the oldest and largest charity bike rides in Europe. Around 25,000 cyclists will participate in the legendary ride that will take them through country lanes and finish by the sea. Meanwhile, this year Pippa will help BHF through fundraising activities like Roll out The Red auction that launched online last week.

The brunette beauty last year collaborated with British designer Tabitha Webb to create an exclusive floral tea dress and scarf to help raise money for “research.” The dress and matching cashmere scarf which is already sold out is being auctioned. The winning bidder will also receive a signed photograph of Pippa in the dress.

Bidding for the designer stuff worth 390 pounds ($568.32) will continue till Feb. 11. The money raised will go towards life-saving research into heart and circulatory disease. Pippa will also attend the charity’s annual Roll out The Red ball. The ball will be hosted by Natasha Kaplinsky, where Pippa will give a welcome speech.
