The 600km course has teams trekking, kayaking and biking in Tierra Del Fuego (translation: Land of Fire), the Karukinka Reserve, Cordillera Darwin and in the Beagle Channel.
The ongoing race is scheduled to finish for the remaining competitors on February 17, with eight teams (five have dropped out) still trying to complete the course before the time cut-off. Last year's finish rate was 30 percent.
