Tennis ace Roger Federer faces a prospect more daunting than a five-setter with Rafael Nadal: a day of survival in the brutal Swiss Alps in Running Wild with Bear Grylls.

While Switzerland is Federer’s homeland, he admits the adventure – shown on 12 July, with another chance to see it this week – is well outside of his comfort zone.
