Sophie Wessex tells Hello! she's 'ready to go' on 445-mile cycling challenge

The Countess of Wessex is setting off on a cycling adventure come Monday (Sept. 19), when she'll ride an impressive 445 miles from the Palace of Holyroodhouse in Edinburgh to Buckingham Palace. Along with a team of five fellow cyclists from regiments with which she's associated, the trip will raise money for The Duke of Edinburgh's Award. Her father-in-law, The Duke of Edinburgh, and her husband, The Earl of Wessex, will sound the group off before pedalling from Scotland to London in just seven days

It's a challenge that Sophie, 51, has trained hard for since February, fitting in rides around out her work with the 870-plus organisations of which she is Patron.
