Rob Riggle in the Great Basin Desert Running Wild with Bear Grylls: The Challenge : Season 1 Episode 6

Bear puts Rob Riggle through survival tests in the Great Basin to prepare for Rob’s latest movie role. They begin by rappelling from a helicopter to travel west, where Riggle learns the ropes and then faces an even bigger ropes challenge. Once on the canyon floor, Bear teaches Rob river crossing skills, foraging for food and building a rudimentary shelter. The next day, Rob must evade being spotted by Bear or face his fear of skydiving.
