He has braved a training session with the Paras, flown a fighter jet and is used to broadcasting live to millions of Americans.
Vincent hopes the show will boost his UK profile
But TV presenter Tim Vincent is about to face his biggest challenge yet - wearing lycra on ITV's Dancing on Ice.
Vincent, 35, from Wrexham, was so concerned about the outfits he sought reassurance from the show's producers.
He said: "My perception was lycra and spangles. They told me I can do as much or as little as I want."
The former Blue Peter host added: "I know that Dancing on Ice can become a celebration of campness with all the costumes, which I'm not so keen on.
"Apparently all the blokes say that absolutely every year, and they start off with a couple of sequins and end up looking like Dame Edna Everage.
"I'm waiting with interest to see if that happens but I've seen my first costume and it's very conservative in the world of ice skating, which to be honest I'm happy about."
The presenter has spent the last three years working in America, where he hosts NBC's primetime entertainment show Access Hollywood.
While most of his ice-dancing competitors have been training for several months, his US commitments meant he was not able to return to the UK until six weeks ago.
"It's not an excuse," he added.
"It's just meant I've had to try and cram more in.
Vincent insists there is "nothing going on" with partner Victoria
"You either get into it or you don't. I'm a typical bloke from Wrexham who usually has to be drunk to get on the dance floor.
"I finished a live show for network TV in America - and I'm much more nervous about skating for one minute than I was about doing that."
Vincent has been paired with Russian skater Victoria Borzenkova.
But with the relationships between dancing partners often attracting as much attention as the performances themselves, he said: "There's nothing going on.
"There's no torrid affairs going on with anyone on the show. They haven't got time to flirt."
Vincent admits the chance to boost his profile in the UK was a big attraction when considering whether to join the show.
He said: "Definitely. That was the main reason to do the show.
"There's limited shows where you can get yourself across.

"It's a feel-good show that everyone in the family wants to watch."
Despite his hectic schedule, Vincent managed to spend seven days with his mother Kathy at her home in Marchwiel, Wrexham, over Christmas.
But she will not be among the studio audience when her son takes to the ice for the first time on Sunday.
He said: "Mum is incredibly nervous so I don't really discuss it with her. She thinks she might put me off.
"I'm like, 'Mum, there's 11 million people going to be watching me in lycra - one more won't make a difference.'
"I don't think she'll go to the first show, but she will probably go to the second one."
Dancing On Ice begins on Sunday on ITV1 at 1750 GMT
