The young Royal ran for Children In Crisis wearing a lime green tutu
Princess Beatrice helped set a new record at the London Marathon yesterday, as she stepped out in a lime green tutu and matching fluorescent leg warmers.
The young royal took part in aid of her mother's charity, Children In Crisis.
Running the 26-mile course tied to 30 friends by bungee cord, the Princess formed part of the largest number of runners to finish the marathon tied together.

The giant green caterpillar was led by sponsor Richard Branson's two children, Sam and Holly.
Beatrice's boyfriend, Dave Clark, also took part.
And as well as being part of the record-breaking line-up, beautiful Bea was also the first ever member of the royal family to run the London Marathon.
Her proud parents, Prince Andrew and the Duchess of York, as well as sister Eugenie, looked on from the sidelines, snapping pictures of exhausted Beatrice as she crossed the finish line.
And the beaming Duchess even revealed that next year she might be taking part.
‘For so long I've been trying to get her fit and now she's showing me up today,' she said of Beatrice.
‘I've just decided that if she's such a good role model to me then next year I'm going to do it.'
