This week on Running Wild, Bear Grylls and Cynthia Erivo are “defying gravity” as they traverse a variety of caves and other icy terrain. On top of the highest peaks in Wales, where Grylls trained for the British Special Forces, he teaches the singer-actress to rappel through the caves on her own with an oxygen monitor.
The new episode premieres on July 23rd at 9/8 central on NatGeo. Watch this exclusive clip from Erivo’s solo trip into the cave. Will she make it out before she runs out of oxygen?
