The team - which also included organiser David Walliams and fellow comedians Russell Howard, Patrick Kielty and Jimmy Carr plus actress Miranda Hart, – crossed the finish line, raising £1 million for their cause in the process.
Posing at the Land's End signpost, the exhausted team could finally rest after cycling for 82 hours and battling gruelling conditions on the way.
Since setting off from John O'Groats they've faced blizzards, snow capped mountains and temperatures hitting minus 15C.
Waiting to greet the man behind the challenge, David, was his model fiancée Lara Stone. After receiving a kiss and hug from the stunning blonde, David said: "It has been an amazing challenge, so much harder and more gruelling than any of us thought it would be.
"To have raised a million pounds in four days is a fantastic thing - thanks so much for everyone who sponsored us, it kept us going."
The money from the challenge will go to helping vulnerable people living incredibly tough lives here in the UK and in some of the world's poorest countries.
