Airdate: Running Wild with Bear Grylls: The Challenge.

Bear Grylls returns to National Geographic with Running Wild with Bear Grylls: The Challenge.

This season he teaches essential survival skills to celebrity guests that they have to master and use in a high-stress situation.

Episode 1 features Natalie Portman and follows weekly with Simu Liu, Ashton Kutcher, Florence Pugh, Anthony Anderson and Rob Riggle.

This season, guests will not only be pushed physically and mentally — like plunging into a frozen lake in the Canadian Rockies or foraging for food in the deserts of the Great Basin — but Bear will be testing each on their survival skills. This time, they will be tested beyond other guests: after Bear teaches each of them a key set of skills, they will then have to master them on their own and deploy those skills at a high-intensity moment to earn their extraction from the wilderness.

Episode 1: Natalie Portman in Southern Utah
Bear takes Academy Award® winner Natalie Portman into the slot canyons of Southern Utah. Their adventure begins when Bear leaps from his helicopter onto Natalie’s 4×4. They trek into the Escalante desert, where Bear teaches Natalie piton placements, rope system transfers and fire starting while descending various canyons. Natalie uses her new skills as they ascend a mountain and attempt to light a signal fire for extraction.

Monday August 15 on National Geographic at 8.30pm.
