Princess Beatrice got her running shoes on at the weekend to part in a five-mile race on Sunday.
The young royal was competing alongside 5,000 members of the public who had been chosen to inaugurate the athletics track in the newly renovated Olympic Stadium in Stratford, East London.

"I am thrilled to be able to play my part in such a historic occasion and it is fantastic to see the incredible transformation that the Olympic Park has undergone," she told crowds as runners took their positions.
"I, like so many others running on the day, know that the experience of being one of the first to cross the Olympic finish line is an extraordinary moment in what promises to be a memorable year for the nation".
After sounding the klaxon to start the race, the Queen's granddaughter then joined the throng to complete the task in a respectable 45 minutes 45 seconds – crossing the finish line to the sounds of Chariots of Fire.
The jog won't have been too taxing for Beatrice, who is used to these kinds of sporting events.
In 2010 she became the first member of the royal family to run the London marathon, raising money for the charity Children in Crisis.
