World's Toughest Race: Eco-Challenge Fiji plot
This ultimate team adventure race and survival competition pits participants from around the world in a series of grueling activities against each other and themselves in the island state of Fiji. Specifically, it is a record of a multi-day expedition race in which 66 teams of four people race non-stop with little to no sleep over mountains, jungles, rivers and oceans. All members of a team must complete the race; if one team member stops, the whole team will be disqualified.
