Martin Johnsrud Sundby has filled the arena with 56 fearless celebrities. Through 55 competitions, they will fight to become "system man out."

Gross motor skills are just as important as fine motor skills, and every day offers a new opportunity to compete in a completely new discipline.

Contestants must keep their cool while solving each task as quickly as possible.

Who can handle the pressure when it matters most? In the grand finale, many of the season's most demanding exercises are combined into one.

The remaining participants will be tested in their sense of location, construction technique, lung capacity and driving skills.
