For two adrenaline junkies attempting to circumnavigate the globe using every conceivable mode of transportation, it's not the destination that counts: it's the journey itself. Hosts Robert “Boston Rob” Mariano and Dennis Anderson must get themselves around the world in 80 different ways, from rickshaws and hovercrafts to hang gliders and barrels. Sometimes, getting there is half the fun. In this series, it’s an epic challenge.
