Royal Run

The Australian-born Royal, 50, donned slim-fitting activewear as she ran one mile [1.6 kilometres] and mingled with the crowd.

' Mary revealed in an interview about meeting the heir to the Danish throne. I didn't know he was the Prince of Denmark. Half an hour later someone came up to me and said, "Do you know who these people are?" Crown Princess Mary of Denmark looked incredibly fit as she took part in the Royal Run in Kolding, Denmark on Monday.
