Four contestants are taking part in the celebrity special, just like in regular episodes of Gladiators.
They are TV presenter Joel Dommett, actor and comedian Ellie Taylor, comedian Rob Beckett and broadcaster Louise Minchin.
TV presenter Rob Beckett said his friends and family “laughed in my face” when he told them he was signing up for the Gladiators Celebrity Special.
He added: “I am trying to challenge myself a bit more on the things I’m scared of, like heights.
“By doing these challenges I feel like it’ll help me get over those fears and it’s a good example for my kids as well, to give it a go and show that you’re not scared and you can conquer your own fears.”
