Season 3
The brain-child of Reality-God, Mark Burnett, brings to TV the gruelling and highly-competitive sport of adventure racing. Teams of 4 must get through tough terrain, racing for 6-12 days, for hours on end. Teams complete the race as soon as all 4 members pass the finish line.
If a team loses a member they are unable to carry on. On Eco-Challenge teams are required to have both males and females. Racers have to be ultra-fit to race through forests, mountains and rivers and to deal with all the weather that is thrown at them. In addition to physical strength they have to have good navigation skills and the will to go on through injuries and seemingly insurmountable obstacles.
Also thrown into the mix are struggles with team dynamics and personal relationships which are tested under the extreme conditions. Season 3 saw the racers strugling in Candadian terrain and is cited by many racers as the toughest race they'e competed in.
