Watch the New, Brutal ‘World’s Toughest Race' Trailer

Amazon Prime just released the trailer for their upcoming epic adventure World's Toughest Race: Eco-Challenge Fiji and it looks absolutely crazy.

The 10-episode series, hosted by Bear Grylls, pits 66 teams from 30 countries against each other in a non-stop race across hundreds of miles in the jungles, mountains, rivers, and ocean of Fiji. The race is a 24/7 ordeal that takes place over 11 days.

"I have no clue what to be afraid of," one of the contestants ominously says in the clip. "I'm about to find out."

In other words, the World's Toughest Race: Eco-Challenge Fiji is about perseverance. A diverse group of teams and competitors will test the limits of human physical and mental endurance -- at one point someone admits they've only had four hours of sleep in as many days, and at another someone seems to teeter on the brink of consciousness. Along the way, viewers are introduced to some of the team members, including a self-described "tough chick," a man who was diagnosed with Alzheimer's, a father and son duo, and a few "strong" Indian women. This year also features gay Black triathlete Coree Aussem-Woltering as a member of Team Onyx, the first all-Black team to compete in the challenge. Woltering does not appear in the trailer but is known for his love of racing on any surface, often in his "signature Speedo and a friendly smile" according to North Face, a brand that he works with.
