Forget your 'Big Brother' and your 'I'm a Celebrity', they're a piece of cake compared to Channel 4's The Jump. The competition saw barely famous faces competing against each other in ski-jumping and speed skating and not many of them came out with all of their limbs in tact.
Over its four series', 34 celebrity contestants injured themselves on the show. Injuries included Brian McFadden breaking his ribs, gymnast Beth Tweddle ended up with a broken vertebra, swimmer Rebecca Adlington dislocated her shoulder, actress Tina Hobley suffered multiple breaks, Made in Chelsea star Mark-Francis Vandell fractured his ankle, former athlete Linford Christie pulled his hamstring, Girls Aloud star Sarah Harding had ligament damage while poor Vogue Williams didn't even get a chance to make it to the live shows as she had to bow out of the competition due to a knee injury she got in training.
So yeah, it's brutal.
Thankfully though, Channel 4 has called time on the reality competition, or at least for now, saying it will be taking a "rest" in 2018. No doubt everyone needs it.
The broadcaster said that while the programme had been "successful" it would not be returning in 2018 so it wouldn't clash with the Winter Olympics in South Korea.
A spokeswoman for Channel 4 said: "The Jump has been a hugely successful brand for Channel 4 over the last four years.
"However, with such a huge amount of winter sport on screen at the start of 2018 we have decided to rest the show for the year."
TV insiders are saying though that the show will be axed for good as the broadcaster has to deal with medical costs and insurance plans for the stars taking part.
A source told The Sun: "The fact Channel 4 have decided against bringing it back next year suggests it’s not a loved property.
"If it was getting big enough numbers or deemed an important show, it would be locked into the schedule every year like The X Factor or I’m a Celebrity.
"By 2019, Channel 4 will have a brand new chief who’ll want to make a mark with hot new shows of their own.
"The writing appears to be on the wall. Resting The Jump for a year makes it easier to quietly cancel the show altogether."
