AFTER shedding eight stone, beating cancer and enduring six failed IVF attempts, Hayley Black is used to overcoming obstacles.

So when faced with “Rake in the Face”, “Tight Rope of Terror” and “The Dread-mill” on BBC1 game show Total Wipeout, she took it all in her stride...dressed as superhero Wonder Woman.

NHS worker Hayley, 36, will be seen by seven million viewers getting drenched in water and splatted in mud on the popular It’s a Knockout-style programme on January 22, at 6pm.

The mum-of-one, of Castle View Road, Canvey, beat 10,000 hopefuls for a place on the latest series of the teatime show, which is filmed in Argentina.

The show sees contestants battling it out on a near-impossible water obstacle course to win a £10,000 prize. Hayley, who shrunk from a size 26 to a svelte size eight in 2005 after losing eight stone in a year, had a good reason for putting her name forward.

She said: “I entered because my six year old son, Kai, loves the show.

“He said to me ‘Mummy, you should do it’.

“I didn’t think I had a chance, so when I got the call I was thrilled.”

Hayley, who has beaten skin cancer and suffered several ectopic pregnancies, spent a week in Buenos Aires filming the show, where she had to scale giant inflatable devices and endure 20ft falls into a water pool.

She added: “Some of the contestants dress up to make it more fun, so I wore a Wonder Woman costume as that’s what my friends have nicknamed me.

“After going through cancer and all the other things I try to make everything as much fun as possible now.”

The show is fronted by Top Gear presenter Richard Hammond, but Hayley didn’t get to meet him. She said: “He does all his voice-over work in the London studio but we met his co-presenter Amanda Byram, who was with us on the course. She was lovely.”

Hayley says it was one of the best experiences of her life.

She said: “It was so much fun, but it’s a lot harder than it looks on television. It takes an incredible amount of stamina to make it round the course.”
