Famed adventurer, writer and television host Bear Grylls is back for a second season of "Running Wild with Bear Grylls." In the premiere episode, Bear takes Oscar nominee Kate Hudson ("Glee") on an adventure she will not soon forget. Their 48 hour journey finds them in the midst of the Dolomites, one of the most treacherous mountain ranges in Italy. As they hike toward the Austrian border on snow-covered exposed rock cliffs, they make some historical discoveries and work together to survive the elements. Kate also gives Bear a peek into her unique upbringing. .
