Twenty-time Grand Slam winner Roger Federer will swap the luxurious lifestyle of five-star hotels for wild life when he ventures the Swiss Alps alongside global adventurer and best selling author Bear Grylls.

Federer will be among the host of celebrities on the latest installment of Running Wild with Bear Grylls, which will also include Hollywood stars Lena Heady, Don Cheadle, Joseph Gordon-Levitt and Uzo Aduba.

The first episode of the series will have Federer discussing memories of raising two sets of twins, to a special game of ping pong, to dropping down into a gorge and eating fish eyeballs.

“I got an address, somewhere in the Swiss mountains - that's all I know. This is like before a match, now, so I start to feel the pulse going boom-boom. I might look like a tough guy on the tennis courts, but I'm actually very scared of a lot of things in life. There's gonna be scary moments for me, so (Bear) just hold my hand!" Federer says on the show.

“There's gonna be some scary moments, I know that, so I do hope that the skill set from tennis comes into play in a big, big way today! I need to do other things than just play tennis all the time,” adds Federer.

Running Wild With Bear Grylls premiers on September 20 at 21:00 hrs on Discovery Channel and Discovery World HD.
