Running Wild with Bear Grylls: The Challenge S02E03 - Cynthia Erivo in the Brecon Beacons Mountains

Bear Grylls takes singer-actress Cynthia Erivo to the highest mountains in Wales, where Bear trained in the British Special Forces. Bear teaches Cynthia how to rappel into and navigate a labyrinth of caves before they traverse a frigid and thunderous waterfall. On day two, Cynthia uses the skills she learned on day one to embark on her own, find Bear, and make it to their extraction.
