By taking part in the Antarctic Ice Marathon, Friedhelm Weidemann and heating technology company Vaillant are setting an example for climate protection.

A true extreme athlete

At 55, Friedhelm Weidemann has completed almost 300 marathons all over the world.
His goal: to join the Seven Continents Club.


He still has two continents to go: South America and Antarctica.
It will be the coldest run of his life.
