After a lot of anticipation and several frantic dashes across the nation by Kathryn Thomas, all of the Series 11 Operation Transformation leaders are now in place.

The final five leaders joined Ray in studio on The Ray D’Arcy Show to tell him how they’re feeling in the run-up to the show.

On the team this year are Mary Diamond from Mayo, Wayne O’Donnell from Cork, Felicity Moroney from Dublin, Sarah O’Callaghan from Cavan and David Cryan from Dublin.

Mary Diamond
Age: 52
Location: Kiltimagh, Co. Mayo
Weight: 13 st

Mary is 52-years-old and runs a Montessori in her garden. On the assessment day, Mary fainted during the 'Circle of Truth', a session with psychologist Eddie Murphy.

Though she’s fine now, it took her (and everyone) by surprise. "I’ve never fainted before in my life. I don’t know where that came from. I wasn’t looking for attention. Really I wasn’t," she said.

Age: 30
Location: Artane, Co. Dublin
Weight: 18 st 9 lbs

Felicity is 30-years-old and has become quite sedentary in terms of exercise.

"Monday to Friday – no [exercise]. Unless I’m just running up and down the stairs, running around the office."

Wayne O'Donnell
Age: 28
Location: Mallow, Co. Cork
Weight: 17 st 12.5 lbs

Wayne is 29-years-old and is recovering from several serious injuries which he thinks have held him back, including a broken arm. He lives at home with his parents.

"I suppose there’s a stigma and a lot of people say ‘Oh, you’re an only child and you’re living at home with your Mam and Dad’ but I suppose the way society’s gone now there’s a lot of my friends, you know, moving back home because of the price of mortgages."

Weight: 12 st 3.5 lbs

Sarah is 27-years-old and a cancer survivor.

"Side-effects for me now, I haven’t really got many as such…what’s really affected me after it is more my head.

"A lot of people can kind of compare with me, you know, the fear. The fear of it coming back."
