Contestants from all over the world braved the cold and the heat in a sauna marathon. The competition pits teams of four against each other with the aim of running from one sauna to the next. With a map at hand, they have to enter each sauna for at least three minutes in minus two degrees temperatures. Each team has to complete 19 sauna sittings. Diving head first into ice pools grants team extra points.
