Mo Farah was knocked to the ground as fish guts were poured all over him during the latest stomach-churning I’m A Celebrity trial.
The Olympian took on the terrifying Fort Locks trial in a bid to win meals for his fellow contestants on the ITV reality show.
Before starting, he admitted that he felt the pressure to do well and that it was “not knowing” that frightened him.
“Everyone's done well so far... I don't want to be that person and let the team down and I can't feed them. I'll just do my best and that's all I can do,” he told the others.
Hosts Ant and Dec told the runner he had to retrieve stars that were locked within “hell holes” built into the castle walls. And all manner of creatures would be thrown into the mix.
Farah seemed fine as he rummaged around in the first hole – which was full of worms - but looked disgusted and started to groan when he encountered fish innards and locusts.
The next key he needed was concealed in slime, and as the star unlocked the grate, he was knocked to the ground by fish guts tumbling down on him.
Farah went on screaming and shouting as he got to his feet and carried on with his grisly task, as Ant and Dec dissolved into giggles.
When the trial finally ended, the athlete had secured nine stars.
He seemed disappointed, saying that the hardest element was "just not knowing (what was) on the other side".
"A lot of the time it was worse in your head than it was in the hole," laughed Dec.
And it wasn’t only Farah facing his fears during Friday’s show, with all of the contestants taking part in a live trial.
The Royal Tournament was a battle of the sexes, with the women and men up against each other in a series of challenges that included bobbing for coins in offal and enduring the dreaded coffins full of bugs.
In the end the men secured more stars and were rewarded with a lavish banquet, while the ladies were told to expect the usual rice and beans.
This year’s series of the ITV show has moved from Australia to Gwrych Castle in Wales because of the coronavirus pandemic.
I’m A Celebrity... Get Me Out Of Here! continues tomorrow night on ITV.
