Royals Princess Beatrice Hits Triathlon Summit: 'I Finally Made It' The princess is helping raise funds for a youth charity By Simon Perry Published on September 29, 2016 04:30 PM Share Tweet Pin Email Photo: Source: Princess Beatrice/Twitter She did it! Princess Beatrice celebrated on Thursday after completing a grueling physical challenge for charity. The super-fit princess, 28, triumphantly tweeted, “After swimming 3,300m [two miles] biking 140km [87 miles], running a half marathon and hiking up mount Etna I finally made it. @strivechallenge @bigchange_” There is a New Princess in Kensington Palace! The triathlon followed a swim off the coast of Sicily on Tuesday, where Beatrice showed off a “b” on her right hand for the charity Big Change. Bea cofounded the charity with siblings Holly and Sam Branson. (Their dad is business tycoon Sir Richard, who also completed the event.) When crossing the finish line, Sir Richard Branson said, “I have just finished the toughest physical and mental test of my life. The Virgin Strive Challenge is complete! Together with an inspiring group of individuals – including my children Holly and Sam, and my nephew Noah – I have traveled from the base of the Matterhorn in Switzerland to the summit of the Mt Etna, under human power. There were moments of extreme frustration, but equally moments of pure joy. I’ve met some many wonderful people along the way, and challenged myself in ways I never thought possible. While we’re sore, raw and tired, we have huge smiles on our faces and we’re already looking forward to our next adventure.” • Want to keep up with the latest royals coverage?
