Eco-Challenge

Eco-Challenge: The Expedition Race is a multi-day expedition length adventure race in which teams of four (five in the early years) competed. It originally aired on Discovery Channel from April 1, 1995, to April 11, 2002. Based closely on the Raid Gauloises adventure race, the broadcast of Eco-Challenge led to the popularity of adventure racing.

The race returned in September 2019, taking place in Fiji. The new series, under the title World's Toughest Race: Eco-Challenge Fiji, premiered on August 14, 2020 on Amazon Prime Video.
