There are many things to admire about Princess Beatrice, from her ultra-glossy hair to her heart-warming approach to step-parenting, but there's one specific achievement that sets her apart from the other royals.
In 2010, Sarah Ferguson's daughter became the first royal ever to complete the London Marathon, running the gruelling 26 miles in honour of the Children in Crisis charity. Not only did Beatrice run the race, she did it dressed as a caterpillar!

The royal was one of 33 runners who made up a human caterpillar, decked out in a neon green skirt and a hat with her name on it – nobody can say Bea isn't a good sport!
It may come as a surprise that none of the other royals have completed a marathon, especially given that many of them are keen sportspeople.

Bryony asked the mother-of-three if she would do the run, to which Kate answered: "Oh no, security and all that."
Sophie Wessex tried her hand at the challenging run in 2020, taking on the first mile and a half of the virtual London Marathon, in honour of the charity Mencap, of which she is a patron.
