Groats on the tip of Scotland to Land

They were among a group of celebrities taking part in a non-stop relay from John O'Groats on the tip of Scotland to Land's End in Cornwall.

They reached their final destination on Thursday at 1850 GMT.

"It was tough, we were cycling through the night at minus 15 degrees sometimes," Walliams said afterwards.

The Little Britain star added: "We're all shattered. But it was great working as a team. There were no egos.

"We were all supporting each other a lot. We've all shared something quite special together."

Miranda Hart, Russell Howard, Patrick Kielty and Jimmy Carr also took part in the four-day fundraising event.

The stars cycled night and day on their bikes and experienced extreme weather conditions, such as blizzards and heavy rain.

The team also suffered cuts, bruises and saddle sores.

Big Brother host McCall said she was still "buzzing" from the challenge.

"We all got emotional when we came into Land's End. I have walked away from this with some new best mates. Ask me right now and I would say 'yes I would do this again'. I am on such a high still, I kind of want to do it again."
