Switzerland's tennis legend Roger Federer joined British adventurer Bear Grylls on a trip through the Swiss Alps, with the pair descending a frozen waterfall and using tennis rackets as snowshoes to cross a frozen lake. After a snack of frozen fish eyeballs, the two ascended a sheer cliff to make their only way home.
On the way Roger shared details of his private life, including amusing aspects of raising two sets of twins and his struggle to develop an on-court balance that led to an unmatched string of Grand Slam victories.
