450 miles, done!

Sophie, Countess of Wessex rode into Buckingham Palace on Sunday, capping off a marathon week of cycling for a good cause.

The super-fit royal mom, 51, crossed the finishing line after setting off from Edinburgh’s Holyroodhouse last Monday, where she admitted to being “nervous.”

And while she appeared to be more than up to the challenge (sometimes fueled by cake!) she did confess to finding the tough steep terrain during some 70 mile-days a “rollercoaster.” Day two last Tuesday “we always knew was going to the hardest,” she told the official British Monarchy Instagram.

“There’s been a lot of hills. There’s been a lot of hills one after the other, just constant hills. I’m really happy to say that we’ve completed day two,” she said.

She tackled the ride to aid the Duke of Edinburgh Award, which is marking its 60th year.
