Davina McCall has admitted that new Channel 4 show The Jump has a certain risk factor – and has said she hopes nobody gets hurt.

The series, which kicks off on Sunday night at 8pm, will see 12 celebrities skiing, bobsleighing, speed skating and tackling other extreme sports in the run-up to the Winter Olympics.

And Davina told the Mirror: “Before I signed up, the production company showed me footage of people who weren’t experts trying to do the sports. I laughed so hard and I thought, ‘Oh my God, I have to present this show’.

“Hopefully no one will seriously hurt themselves, but let’s not deny how dangerous the show is. Health and safety is really strict.”

Those taking part include TOWIE star Amy Childs, Olympic hero Sir Steve Redgrave, retired cricketer Darren Gough and TV presenter Anthea Turner.

5ive singer Ritchie Neville, socialite Henry Conway, former Pussycat Doll Kimberly Wyatt and glamour model Melinda Messenger will also be among those hitting the slopes – with a perilous ‘ski-jump challenge’ awaiting the two lowest scorers at the end of every show.

The show has already been hit by injury, with Flash Gordon star Sam Jones quitting after hurting his arm during training – while reports suggest Henry Conway’s involvement may be in jeopardy due to an injured thumb.

It has also emerged that ITV rejected The Jump two years ago over safety concerns.

“This show was pitched to us two years ago,” an ITV executive told the Mirror, “but in the end we thought the chances of someone famous getting seriously hurt were just too high, so we said no.”
